Abstract

This paper investigates the uniqueness, connectedness and openness properties of spaces of Kähler forms on closed 4-manifolds, extending discussions in \citeLi08,Sal13. Motivated by the Streets--Tian conjecture concerning the existence of Kähler metrics on Hermitian-symplectic complex manifolds, we also study holomorphically tamed symplectic forms, which are symplectic forms tamed by some integrable complex structure. We formulate a parallel question and relate it to the corresponding questions for Kähler-type symplectic forms.
