Forbidden configurations and definite fillings of lens spaces
Antony T. H. Fung, JungHwan Park
We study definite fillings of lens spaces. We classify the lens spaces for which every smooth negative-definite filling satisfies \[ b_2(X)\ge b_2(X(p,q))-1, \] where…

Integer surgeries rational homology cobordant to lens spaces
Antony T. H. Fung
The Cyclic Surgery Theorem and Moser's work on surgeries on torus knots imply that for any non-trivial knot in , there are at most two integer surgeries that produce a lens sp…
