On homology planes and contractible -manifolds

Rodolfo Aguilar Aguilar, Oğuz Şavk

We call a non-trivial homology sphere a Kirby-Ramanujam sphere if it bounds both a homology plane and a Mazur or Poénaru manifold. In 1980, Kirby found the first example by proving…

A survey of the homology cobordism group

Oğuz Şavk

In this survey, we present most recent highlights from the study of the homology cobordism group, with a particular emphasis on its long-standing and rich history in the context of…

Almost simple linear graphs, homology cobordism and connected Heegaard Floer homology

Çağrı Karakurt, Oğuz Şavk

Continuing our previous work, we effectively compute connected Heegaard Floer homologies of two families of Brieskorn spheres realized as the boundaries of almost simple linear gra…

Classical and new plumbed homology spheres bounding contractible manifolds and homology balls

Oguz Savk

A central problem in low-dimensional topology asks which homology -spheres bound contractible -manifolds or homology -balls. In this paper, we address this question for pl…

More Brieskorn spheres bounding rational balls

Oguz Savk

We call an integral homology sphere bounds a rational homology ball if it is obstructed from bounding an integral homology ball. After Fintushel and Stern'…

Ozsvath-Szabo -invariants of almost simple linear graphs

Cagri Karakurt, Oguz Savk

We describe an effective method for simultaneously computing of -invariants of infinite families of Brieskorn spheres with .
