Using the idea of a generalized Kaehler structure, which is a pair of commuting generalized complex structures, we construct bihermitian metrics on the projective plane and the product of two projective lines, and show that any such structure on a compact 4-manifold M defines one on the moduli space of anti-self-dual connections on a fixed principal bundle over M. We highlight the role of holomorphic Poisson structures in all these constructions.

  1. On the rigidity of special and exceptional geometries with torsion a closed $3$-form

    math.DG 2025-11 unverdicted novelty 7.0 of 10

    Riemannian manifolds with a closed parallel torsion 3-form are locally N × G (G semisimple), enabling simplified proofs and explicit classification of strong G2, Spin(7), and certain 8D HKT manifolds.

  2. Geometry and symmetries of Hermitian-Einstein and instanton connection moduli spaces

    hep-th 2025-01 conditional novelty 6.0 of 10

    Holomorphic, torsion-parallel vector fields on KT manifolds induce Killing and holomorphic vector fields on Hermitian-Einstein moduli spaces, which become toric or QKT fibrations under extra closure conditions.
