Canonical almost-K\"ahler metrics dual to general plane-fronted wave Lorentzian metrics
Abstract
In the compact setting, Aazami and Ream Aazami:2022th proved that Riemannian metrics dual to a class of Lorentzian metrics, called (compact) general plane-fronted waves, are almost-K\"ahler. In this note, we explain how to construct extremal and second-Chern-Einstein non-K\"ahler almost-K\"ahler metrics dual to those general plane-fronted waves.
