Abstract

We classify compact self-dual almost-K\"ahler four manifolds of positive type and zero type. In particular, using LeBrun's result, we show that any self-dual almost-K\"ahler metric on a manifold which is diffeomorphic to CP2\mathbb{CP}_{2} is the Fubini-Study metric up to rescaling. In case of negative type, we classify compact self-dual almost-K\"ahler four manifolds with JJ-invariant Ricci tensor.
