ABC-KLM Network in Algebraic Geometry, Boundary Conformal Field Theory and Noncommutative Geometry Meetings Information about the Network Mailing List Meetings Future meetings: Previous meetings: Oxford, January 2004 York, October 2003 Durham, May 2003 Warwick, January/February 2003 ... Swansea, November 2001 Information about the Network The objective of this network is to bring together groups in the UK having a common goal in pursuing the deep connections between mathematics and physics—primarily algebraic geometry, operator algebras and quantum groups in pure mathematics and conformal field theory, string theory and statistical mechanics in mathematical and theoretical physics. The network is initially built around Alessio Corti (Cambridge), Gustav Delius (York), David Evans - coordinator (Cardiff), Nigel Hitchin (Oxford), Shahn Majid (Queen Mary, London), Andreas Recknagel (King's London) and Miles Reid (Warwick). Funding by EPSRC grant GR/R36596/01 will enable individual visits as well as informal one or two day meetings and network workshops. This builds on our previous more ad hoc arrangements which include the workshop in Warwick in September 1999, the

142. Popular Texts Textbook in Problems on Elementary Topology by Viro, Ivanov, Kharlamov and Netsvetaev draft version in postscript. The page also includes several papers on real algebraic geometry. http://www.math.uu.se/~oleg/educ-texts.html

Textbook in Problems on Elementary Topology by O.Ya.Viro, O.A.Ivanov, V.M.Kharlamov and N.Y.Netsvetaev. This is a textbook on Elementary Topology. Still, it is not finished. Hopefully, it will not be yet another textbook. Here is Foreword where we describe the collection of pedagogical ideas and tricks, which can give the first impression about the project. To find out more, take a look on the Table of Contents I would appreciate any criticism, or suggestions either on the general principles or any specific part of the text. The last version of the whole book (a PostScript file) can be taken here Russian version, which is even less complete, can be found here. Configurations of Skew Lines in the 3-Dimensional Space This is a survey of results on projective configurations of subspaces in general position written by Julia Viro and Oleg Viro in the form of a popular introduction to the subject, with much of the material accessible to advanced high school students. However, in the part of the survey concerning configurations of lines in general position in three-dimensional space we give a complete exposition. The same paper in postscript format: Interlacings of Skew Lines Introduction into Topology of Real Algebraic Varieties Postscript files of the first sections of this text: The Early Topological Study of Real Algebraic Plane Curves A Real Algebraic Curve from the Complex Point of View The Topological Point of View on Prohibitions Patchworking A popular paper concerning a technique for constructing real algebraic varieties by gluing pieces together and counter-examples to the oldest conjecture about topology of real algebraic curves (published in the Intelligencer).

151. Research In Geometry & Algebraic Topology geometry and algebraic Topology. http://www.maths.gla.ac.uk/research/groups/geoalgtop/geoalgtop.html

Mathematics Home Research Undergrad Postgrad ... Mathematical Education In many respects, the latter half of the 20th Century has been a golden age of Geometry and Topology, with spectacular advances in the study of manifolds (particularly in dimension 4), Global Analysis including Index Theory, complex manifolds and Algebraic Geometry, including its applications in Number Theory. Increasingly, strong connections with integrable system theory and global aspects of differential equations as well as the remarkable two-way flow of ideas between Geometry and Theoretical Physics are dominating developments. Algebraic Topology has developed important machinery such as cohomology theories including ordinary cohomology, K -theory, cobordism and elliptic cohomology. These are often of use in geometric situations, as well as within Algebraic Topology itself which tends to study much less `rigid' geometric situations than Geometers do. There have also been significant interactions with many areas of Algebra, and indeed much of Algebraic Topology can be viewed as `applied algebra' as well as being a major source of innovative algebraic ideas. Departmental research activity in Geometry and Topology occurs in the following areas.

Thomas Title: Professor of Algebraic Topology College: Robinson College Room: E1.19 Tel: +44 1223 337970 Research Interests: It has long been known that the existence of certain geometric structures on smooth manifolds imposes topological constraints. A deeper question is to ask whether these suffice, and if not, what additional conditions are needed. Examples include Riemannian metrics (with positive scalar, Ricci or sectional curvatures), contact and symplectic forms. In attempting to solve these problems interesting arithmetic questions arise - for example on the role of cubic forms in the construction of symplectic 6-manifolds. Other interests: group cohomology, geometrisation of 3-manifolds, application of topology to number theory. Information provided by webmaster@dpmms.cam.ac.uk
