Connectedness of fibers beyond semitoric systems II: ephemeral singular points
Daniele Sepe, Susan Tolman
In an earlier paper, we proved the connectedness of the fibers of every -dimensional integrable system satisfying both: the action extends the action of an -dimensional…
Connectedness of fibers beyond semitoric systems I: the non-degenerate case
Daniele Sepe, Susan Tolman
In this paper we study the connectedness of the fibers of integrable systems that extend complexity one -spaces with proper moment maps, assuming that every tall singular point…
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…
From Lagrangian Products to Toric Domains via the Toda Lattice
Yaron Ostrover, Vinicius G. B. Ramos, Daniele Sepe
In this paper we use the periodic Toda lattice to show that certain Lagrangian product configurations in the classical phase space are symplectically equivalent to toric domains. I…
