Professor BH Neumann AC FAA FRS (1909-2002) Professor Bernhard Neumann, a Fellow of the Australian Academy of Science, celebrated his 90th birthday on 15 October 1999. He had played a dominant role in mathematics in Australia since his arrival in this country in 1962. Professor Neumann came to Australia to take up an appointment as the Foundation Chair of the Department of Mathematics within the Institute of Advanced Studies of the Australian National University. He and his late wife Hanna taught and influenced many young people with mathematical talent, at both the graduate and undergraduate levels, and their influence spread downwards into the schools. Hanna was Professor and Head of the Department of Mathematics in the then School of General Studies (now the Faculties) at the ANU, and she was also a Fellow of the Academy. Bernhard Neumann's distinguished contributions to mathematics were many and varied, mostly on the theory of groups. His original work is to be found in over 100 papers, but in addition he is the author of two books and numerous reviews, and he wrote essays about a number of famous mathematicians. In his six-volume series, The Selected Works of B H Neumann and Hanna Neumann, are to be found fascinating commentaries of the life work of Hanna and himself, as well as about the many famous mathematicians and colleagues with whom they've been associated. Professor Neumann's long and distinguished career began in pre-war England, following his early studies to the doctorate level in Germany. By the time he arrived in Australia, his eminence had already been recognised through his election to Fellowship of the Royal Society.

BH NEUMANN AWARD FOR Martin Ward The Board of the Australian Mathematics Trust has announced the awarding of a BH Neumann Award for Senior Lecturer in Mathematics at the ANU Dr Martin Ward. This Award, named in honour of Professor BH Neumann, the father of Australian Mathematics, was presented by Professor Neumann at a function at the ANU on the evening of Tuesday 29 June 1999. Professor Neumann, Martin Ward and ANU Vice-Chancellor, Professor Deane Terrell at the Award ceremony. Citation With respect to Australian Mathematics Trust activities, Martin Ward mostly comes under notice as a problem creator for the Australian Mathematics Competition Problems Committee. Martin has been a member of this committee over a number of years, including the earliest years 20 years ago. He is responsible for many of the most challenging questions which have appeared in the paper, some of a geometrical nature (including 3 dimensions), others of a graph theory nature, and others algebraic. Whatever, Martin's questions are distinctive for their freshness and the intellectual (but always apparently achievable) challenge which they provide. Martin almost became a chemist, and in fact first completed a chemistry degree at the University of Melbourne. He then decided that he did not wish to spend his life in a laboratory.

Hanna Neumann geb.: 12.02.1914 in Berlin gest.: 14.11.1971 in Ottawa/Kanada Privates Schule und Beruf Mathematische Leistungen Privates - Schule und Beruf - Mathematische Leistungen Die Freundschaft zwischen Hanna und Bernhard begann im Januar 1933, und entwicklete sich im Laufe der Zeit zu etwas ganz besonderem. Im August 1933 verließ Bernhard Berlin, um nach Cambridge in England zu gehen; es wurde klar, daß Deutschland für Juden für längere Zeit nicht mehr der richtige Aufenthaltsort sein konnte. Ostern 1934 besuchte Hanna ihn in London, wo sie sich heimlich verlobten; schon das Klima in Deutschland und später die Gesetze verboten solche "Mischbeziehungen". Danach wandte Hanna sich wieder ihren Studien zu. Diese Entwicklung hatte außerdem einen direkten Einfluß auf ihr Studium. Hanna hatte zu diesem Zeitpunkt ihre Doktorarbeit anvisiert. Im vierten Semester stand ihre mündliche Prüfung an und sie wurde schon im vorhinein gewarnt, daß eben gerade dieser oben erwähnte Mathematiker ihr "politisches Wissen" prüfen sollte, was von da an zwingend vorgeschrieben wurde. So riet man ihr, das Staatsexamen so schnell wie möglich zuendezubringen, mit dem Ziel bei einem anderen Dozenten zu ihrem "politischen Wissen" geprüft werden zu können. So konnte sie weitermachen und an einer anderen Universität promovieren. p Die ersten Jahre in Großbritannien waren nicht einfach, weil sie eine Familie gegründet hatten und mit ihren ersten produktiven Forschungen begannen. Hanna und Bernhard waren der Meinung, daß sie nicht öffentlich heiraten konnten, solange seine Eltern nicht sicher vor Repressionen waren. Bernhard assistierte zeitweise als Dozent in Cardiff und Hanna ging nach Bristol. Dort arbeitete sie, angeregt durch Bernhard, an einem Problem, das der Beginn ihres ersten Artikels "Über Eliminationsregeln" werden sollte.

36. More General Classes By a theorem of BH neumann, hanna neumann, PM neumann, and G. Baumslag, the semigroupof varieties is a cancellation semigroup with 0 and neutral element http://math.berkeley.edu/~magidin/research/moregen.html

More general classes Back to my homepage Research page Introduction Nilpotent groups ... Solvable groups More gen. classes Preprints Personal info. What's new This is a sort of catch-all section for all the other results I have relating to dominions in the setting of categories of groups. First let me address another specific class of varieties, and then I will indulge in a bit of more abstractness. Simple Groups As already mentioned, P.M. Neumann proved that no category of solvable groups which is closed under quotients can have nonsurjective epimorphisms. However, if we start with the alternating group on five letters A(5) , then B.H. Neumann proved that in the variety it generates (the collection of all homomorphic images of subgroups of powers of A(5) ), the embedding of A(4) into A(5) is an epimorphism, and trivially nonsurjective. See: Splitting groups and projectives in varieties of groups by P.M. Neumann, Quart. J. Math. Oxford (2), By generalizing B.H. Neumann's argument, one can describe the dominion of a subgroup H of a finite nonabelian simple group S in the variety generated by S . Namely, it is the subgroup fixed by all automorphisms of

37. Dominions In Metabelian Groups From a famous theorem of BH neumann, hanna neumann, Peter neumann, and G. Baumslag,every variety of groups can be written uniquely as a finite product of http://math.berkeley.edu/~magidin/research/metab.html

Dominions in metabelian groups Back to my homepage Research page Introduction Nilpotent groups ... Amalgams Metabelian grps. Other results More gen. classes Preprints Personal info. ... What's new The situation regarding dominions in solvable groups is not much better than that concerning amalgams in general, and is certainly much below the situation for nilpotent groups. We do have some interesting results, particularly for the metabelian groups (groups which are extensions of abelian or abelian; equivalently, groups for which the commutator subgroup is abelian; also equivalently, solvable of length at most two). Let G be the free metabelian group on two generators x and y , and let H be the subgroup generated by the commutators [ x,y x,y,x ] and [ x,y,y ]. The commutator subgroup of G contains a free abelian group if infinite rank, and H is a finitely generated subgroup of it. Well, perhaps surprisingly, it turns out that H dominates all of [ G,G ]; that is, the dominion of H in G equals the commutator subgroup of G . Part of the reason this may seem surprising is that this means that H , which is a direct summand of rank three of that countably generated free abelian group actually dominates that entire abelian subgroup and more. And yet, it is normal in its dominion. Somehow, the structure imposed on [

OBITUARY Bernhard Neumann FEATURES CENTREFOLD Bruce Weir NEW COLLEAGUES BOOK REVIEWS CONFERENCES MINUTES ... MATHEMATICAL MINIATURE 20 Mathematics and Music ISSN 0110-0025 OBITUARY Emeritus Professor Bernhard Neumann, AC DSc FAA FRS (15 October 1909 to 21 October 2002) The mathematical community in Australasia lost a distinguished member and patron when Bernhard Neumann died, aged 93, in Canberra late last year. The New Zealand Mathematical Society lost one of its foundation members, who was instrumental in establishing the NZMS in 1974 and was elected as an Honorary Life Member soon afterwards. Bernhard Hermann Neumann was born in Berlin-Charlottenburg, Germany in 1909, and after showing aptitude for mathematics at an early age he studied at university in Freiburg and Berlin, and gained his first doctorate (in group theory) in 1932, at the age of 22. He moved to England in 1933, and two years later completed a second doctorate at the University of Cambridge, from which he also won the Adams Prize. He married Hanna von Caemmerer (another mathematician) in 1938, and the couple had five children: Irene, Peter, Barbara, Walter and Daniel. Peter Neumann and Walter Neumann are also mathematicians well known to many readers of this Newsletter.

NZMS Newsletter 47, December 1989 CENTREFOLD Professor Bernhard Neumann Bernhard Hermann Neumann was born in Berlin on 15 October 1909. After studying at the Herderschule in Berlin and at the University of Freiburg, he obtained his Dr.phil. degree from the University of Berlin in 1932. He emigrated to Britain in 1933 (during a time of political upheaval in Germany), and continued his studies at Cambridge, where he was awarded a Ph.D. in 1935. Meanwhile he became secretly engaged to Hanna von Caemmerer, who had been a fellow student in Berlin, and in 1938 she also left for Britain, where they married. At that time Bernhard held a temporary assistant lecturership at Cardiff, but at the beginning of the Second World War he was interned for some weeks (as an enemy alien); upon his release he joined the British Army, serving in the Intelligence Corps from 1940 to 1945. In 1946 he was appointed as a lecturer at the University of Hull, and in 1948 he accepted a position at the University of Manchester, where he stayed for the next thirteen years. Hanna and Bernhard had five children: Irene, Peter, Barbara, Walter and Daniel. Hanna was able to complete her doctorate at the University of Oxford, and after the war she became an assistant lecturer at Hull, and later (in 1958) she too obtained a position in Manchester. During these years both Hanna and Bernhard established fine reputations as mathematicians, with common research interests in algebra. In particular, their joint paper with Graham Higman (published in 1949) on embedding theorems for groups is a famous one, underlying the theory of what are now known as HNN-extensions. Bernhard was awarded the Wiskundig Genootschap te Amsterdam Prize in 1949, and the Adams Prize of the University of Cambridge in 1952. He gained a D.Sc. from the University of Manchester in 1954 (and Hanna the same from the University of Oxford in 1955), and in 1959 he was elected a Fellow of the Royal Society.
