The log-concavity conjecture for the Duistermaat-Heckman measure revisited
Yi Lin
Karshon constructed the first counterexample to the log-concavity conjecture for the Duistermaat-Heckman measure: a Hamiltonian six manifold whose fixed points set is the disjoint…

Examples of Non-Kähler Hamiltonian circle manifolds with the strong Lefschetz property
Yi Lin
In this paper we construct six-dimensional compact non-Kähler Hamiltonian circle manifolds which satisfy the strong Lefschetz property themselves but nevertheless have a non-Lefsch…

Equivariant symplectic Hodge theory and the -lemma
Yi Lin, Reyer Sjamaar
Consider a Hamiltonian action of a compact Lie group on a symplectic manifold which has the strong Lefschetz property. We establish an equivariant version of the Merkulov-Guillemin…
