Generalized Kähler manifolds via mapping tori (2305.11075v3)

Abstract: Starting from the product of a $3$-torus and a compact K\"ahler (respectively, hyperK\"ahler) manifold we construct via mapping tori generalized K\"ahler manifolds of split (respectively, non-split) type. In this way we obtain new non-K\"ahler examples and we recover the known examples of generalized K\"ahler solvmanifolds. Moreover, we investigate the formality and the Dolbeault cohomology of the generalized K\"ahler mapping tori.
