On a symplectic generalization of a Hirzebruch problem
Leonor Godinho, Nicholas Lindsay, Silvia Sabatini
Motivated by a problem of Hirzebruch, we study -dimensional, closed, symplectic manifolds having a Hamiltonian torus action with isolated fixed points and second Betti number eq…

Classification of Hamiltonian -actions on compact symplectic orbifolds with isolated cyclic singular points in dimension four
Leonor Godinho, Grace T. Mwakyoma-Oliveira, Daniele Sepe
In this paper, we classify Hamiltonian -actions on compact, four dimensional symplectic orbifolds that have isolated singular points with cyclic orbifold structure groups, thu…
