[Ergun Yalcin]

Değerli Liste üyeleri,

Bu hafta Bilkent'te Almanya'dan bir misafirimiz var. Bugün ve Çarşamba günü birer seminer verecek.
İlgilenen herkesi bu seminerlere davet ediyoruz.

Topoloji seminerleri her hafta olacak. Konuşmaların ilanlarını düzenli olarak almak istiyorsanız lütfen bana yazın.

Selamlar,

BILKENT TOPOLOGY SEMINAR

Title: Equivariant bordism of elementary abelian groups.

Speaker: Bernhard Hanke (Augsburg University)

Time: October 5, 2015 Monday 13:40-14:30

Place: Math Department Seminar Room

Abstract: The computation of bordism groups of manifolds equipped with group actions is a classical
topic in geometric topology. We recall the basic definitions and present some new computations
for elementary abelian groups.

DEPARTMENT OF MATHEMATICS COLLOQUIUM

Speaker: Bernhard Hanke (Augsburg University)
Time: October 7, 15:40,
Place: Mathematics Department Seminar Room

Title: Manifolds of positive scalar curvature


Abstract: Curvature is a basic notion in differential geometry, because it
measures the deviation from flat, Euclidean space. This talk deals with
scalar curvature, which can be defined  by the volume growth of small
balls in Riemannian manifolds. We give an overview of some old and new
results concerning Riemannian metrics with everywhere positive scalar
curvature, combining techniques from global analysis, topology, and
general relativity.

There will be tea and biscuits after the talk
