SUMMARY:Geometry & Topology Seminar
CLASS:PUBLIC
DESCRIPTION:OĞUZ ŞAVK\, BOGAZIÇI UNIVERSITY\n\n\"Classical and new pl
 umbings bounding contractible manifolds and\nhomology balls\"\n\nA central
  problem in low-dimensional topology asks which homology\n3-spheres bound 
 contractible 4-manifolds and homology 4-balls. In this\ntalk\, we address 
 this problem for plumbed 3-manifolds and we present\nthe classical and new
  results together. Our approach is based on\nMazur’s famous argument whi
 ch provides a unification of all results\nin a fairly simple way.
