Dear Colleagues,

You are most cordially invited to the Yeditepe Mathematics 25th Year Seminars organized by the Department of Mathematics at Yeditepe University. The details of this week's talk are as follows:

Title: Classical and New Plumbings Bounding Contractible Manifolds and Homology Balls

Speaker:  Oğuz Şavk (Boğaziçi University)

Abstract: A central problem in low-dimensional topology asks which homology 3-spheres bound contractible 4-manifolds and homology 4-balls. In this talk, we address this problem for plumbed 3-manifolds and we present the classical and new results together. Our approach is based on Mazur’s famous argument which provides a unification of all results in a fairly simple way.

Date: Friday, March 5, 2021

Time: 16:00
