[Ergun Yalcin]

Sayin Liste uyeleri,
6-19 Mayis tarihleri arasinda McMaster Universitesinden
Ian Hambleton Bilkent Universitesinde ziyaretci olarak 
bulunacaktir. Bu ziyaret sirasinda 9 Mayis Carsamba 
gunu asagida ilanini ekledigim genel semineri verecektir. 
Ayrica 14 Mayis Pazartesi gunu Bilkent Algebraic Topology 
seminerinde "Finite group actions on Kervaire manifolds"
adli bir seminer daha verecektir.  

Butun ilgilenen matematikcileri bu konusmalara davet ediyoruz.

Saygilarimla,

GENERAL SEMINAR

Speaker: Ian Hambleton (McMaster University)

Title:  Symmetry in geometric topology

Abstract: This will be a survey talk about connections 
between the topology of manifolds and the structure of 
their finite symmetry groups. I will describe some work 
on this theme, both old and new, and present some open 
problems for further research.


Date : Wednesday, May 9, 2012
Time : 15:40-16:30
Place: Seminar Room 141

TEA  AND COOKIES WILL BE SERVED BEFORE THE SEMINAR.

>> The Kervaire manifolds are  closed, oriented, almost framed PL manifolds in dimension 4k+2 with Arf invariant 1. In certain exceptional dimensions (2, 6, 14, 30, 62 and perhaps 126) there exist smooth Kervaire manifolds. The talk will be about the existence  of free smooth or PL actions of finite groups on Kervaire manifolds, starting with the existence of free involutions. In contrast with a product of spheres S^{2k+1} \times S^{2k+1}, it turns out that the Kervaire manifolds have very restricted symmetry. This is joint work (in progress) with Diarmuid Crowley.
