Boğaziçi Üniversitesi Matematik Lisansüstü SeminerleriBrieskorn Spheres Bounding Homology Balls Oğuz Şavk A classical question in low-dimensional topology asks which homology $3$-spheres bound homology $4$-balls. We address this queston to Brieskorn spheres $\Sigma(p,q,r)$ which are defined to be links of singularities $x^p+y^q+z^r=0$. In this talk, we will present several families of Brieskorn spheres which do or do not bound integral and rational homology balls.
