Yeditepe Üniversitesi Matematik Bölümü 25. Yıl SeminerleriClassical and New Plumbings Bounding Contractible Manifolds and Homology Balls Oğuz Şavk 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. NOT: Please contact the organizers for the seminar link.
