Finiteness and boundedness of positive monotone Hamiltonian GKM spaces
Panagiotis Konstantis, Silvia Sabatini, Leopold Zoller
In this paper, we establish three finiteness and boundedness theorems for compact positive monotone symplectic manifolds endowed with special actions, called GKM, which general…

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…
