Log-concavity of complexity one Hamiltonian torus actions

Yunhyung Cho, Min Kyu Kim

Let $(M, ω)$ be a closed $2 n$ -dimensional symplectic manifold equipped with a Hamiltonian $T^{n - 1}$ -action. Then Atiyah-Guillemin-Sternberg convexity theorem implies that the image…

The log-concavity conjecture on semifree symplectic S^1-manifolds with isolated fixed points

Yunhyung Cho

Let $(M, ω)$ be a closed $2 n$ -dimensional semifree Hamiltonian $S^{1}$ -manifold with only isolated fixed points. We prove that a density function of the Duistermaat-Heckman measure is…
