Solving the cohomological equation for locally hamiltonian flows, part I -- local obstructions
Krzysztof Frączek, Minsung Kim
We study the cohomological equation for smooth locally Hamiltonian flows on compact surfaces. The main novelty of the proposed approach is that it is used to study the regul…
