Rational blowdown graphs for symplectic fillings of lens spaces
Mohan Bhupal, Burak Ozbagci
In a previous work, we proved that each minimal symplectic filling of any oriented lens space, viewed as the singularity link of some cyclic quotient singularity and equipped with…

Weighted homogeneous singularities and rational homology disk smoothings
Mohan Bhupal, Andras I. Stipsicz
We classify the resolution graphs of weighted homogeneous surface singularities which admit rational homology disk smoothings. The nonexistence of rational homology disk smoothings…

Symplectic fillings of links of quotient surface singularities
Mohan Bhupal, Kaoru Ono
We study symplectic deformation types of minimal symplectic fillings of links of quotient surface singularities. In particular, there are only finitely many symplectic deformation…
