Mathematician's Portrait: Professor Emeritus H.S.M. Coxeter Prof. Coxeter celebrates 60 years at the University of Toronto Professor Emeritus H.S.M. Coxeter B.A., Ph.D., D.Sc., LL.D., D. Math, FRS, FRSC H.S.M. Coxeter was born and educated in England, but his professional connections with North America began early. Shortly after finishing his doctoral studies at Cambridge University , and while he was a research fellow there, he spent two years as a research visitor at Princeton University . In 1936 he joined the Faculty of the University of Toronto, and despite numerous mathematical visits to centres around the world, has remained here ever since. Undoubtedly the world's best known geometer, Professor Coxeter has made contributions of fundamental importance to the Theory of Polytopes , Non-Euclidean geometry, Discrete Groups, and Combinatorial Theory, to name the areas of mathematical research for which he is best known. Endowed with artistic gifts himself, particularly in music, he gives to all mathematics that he touches an aura of beauty. He is equally at home lecturing to colleagues at an international research conference, or to gifted high school mathematics students. Along with a large and growing volume of research publications, his expository books and articles on geometry and on recreational mathematics are very popular. He is living proof that a great scholar can also be a great communicator. Numerous honours have come to Professor Coxeter in his long and illustrious career. He is a Fellow of both the

It has facilities for converting expressions from one symmetric function basis to another, for applying standard operations such as scalar products, inner tensor (or Kronecker) products, and plethysm. Beginning with Version 2.0, it has general facilities for adding user-defined bases to the environment, such as Hall-Littlewood functions, zonal polynomials, or Macdonald's two-parameter symmetric functions.

FIRMAMENT "Let there be a Firmament in the midst of the waters, and let it divide the waters." Genesis: Chapter 1: verse 6 On February 9th 1997, the late Professor Donald Coxeter of the University of Toronto celebrated his 90th Birthday. I was delighted that through the generosity of Robert A. Hefner III and Damon de Laszlo, the Fields Institute for Research in Mathematical Sciences placed my Symbolic Sculpture INTUITION outside their building to mark the day. (ADDED LATER: See the bottom of this page for links to obituaries for Professor Coxeter) When I met Donald he told me about a 'geometric progression' that he had discovered, where spheres were 'mutually tangent' (see Coxeter on 'Firmament ). He asked me if I thought it would be possible to use his findings in a sculpture, and explained that the radii of the spheres are, if the unit is a decimetre, 1.5cm, 2.8cm, 5.3cm, 10cm, 18.8cm, 35.5cm, 66.8cm. I could use only the first five spheres as numbers 6 and 7 in the sequence are too big to handle. I had the 5 spheres spun by a wood turner, and only when I put the jigsaw puzzle together was I able to see the miracle that Donald had perceived through his mathematical vision. I mounted the spheres on a vertical rod capped by a plane set at 23.5 degrees to the horizontal plane, and used an

Positive integers Abel Prize 2004 Posted 2004-03-25 19:53:35 by mnemo The Norwegian Academy of Science and Letters has decided to award the Abel Prize for 2004, jointly to Sir Michael Francis Atiyah, University of Edinburgh and Isadore M. Singer, Massachusetts Institute of Technology. Atiyah and Singer will receive the prize “for their discovery and proof of the index theorem, bringing together topology, geometry and analysis, and their outstanding role in building new bridges between mathematics and theoretical physics.” The Atiyah-Singer index theorem is one of the great landmarks of twentieth century mathematics, influencing profoundly many of the most important later developments in topology, differential geometry and quantum field theory. Its authors, both jointly and individually, have been instrumental in repairing a rift between the worlds of pure mathematics and theoretical particle physics, initiating a cross-fertilization which has been one of the most exciting developments of the last decades.

Four Colors Suffice: How the Map Problem Was Solved by Robin Wilson Average Customer Review: New: List: Buy Used from: The four-color conjecture, formulated in 1852, was among the most popular unsolved problems in mathematics. It stated that only four country colors are needed in any map so that neighboring countries are always colored differently. The first correct proof was completed in 1976 using a computer to verify almost 2000 special irreducible cases. This book describes the history of this problem, and its solution. Standard Mathematical Tables and Formulas (31st Edition) by Daniel Zwillinger Average Customer Review: New: List: Buy Used from: This is an essential (and reasonably priced) reference work that puts a wealth of well-organized math formulas and tables at your finger tips. It has extensive coverage of discrete math, trigonometry, geometry, linear algebra, calculus, special functions, numerical methods, probability, and statistics.
