Self-dual almost-Kähler four manifolds

Inyoung Kim

We classify compact self-dual almost-Kähler four manifolds of positive type and zero type. In particular, using LeBrun's result, we show that any self-dual almost-Kähler metric on…

Almost-Kähler four manifolds with harmonic self-dual Weyl curvature

Inyoung Kim

We show that a compact almost-Kähler four manifold $(M, g, ω)$ with harmonic self-dual Weyl curvature and constant scalar curvature is Kähler if $c_{1} \cdot ω \geq 0$ . We also prove…
