A geometrical structure on even-dimensional manifolds is defined which generalizes the notion of a Calabi-Yau manifold and also a symplectic manifold. Such structures are of either odd or even type and can be transformed by the action of both diffeomorphisms and closed 2-forms. In the special case of six dimensions we characterize them as critical points of a natural variational problem on closed forms, and prove that a local moduli space is provided by an open set in either the odd or even cohomology.

  1. Symmetries and Higher-Form Connections in Derived Differential Geometry

    math.DG 2026-02 unverdicted novelty 8.0

    A derived-geometric definition of p-form connections on infinity-bundles is given via splittings of the Atiyah L-infinity-algebroid, recovering Cech-Deligne cocycles for higher U(1)-bundles.

  2. Generalised Complex and Spinor Relations

    hep-th 2026-03 unverdicted novelty 7.0

    Courant algebroid relations define spinor and Dirac structure relations, with T-duality inducing spinor relations that generalize twisted cohomology isomorphisms and are compatible with Type II supergravity equations.

  3. On Quantum Aspects of 1-Form Symmetries I: BV-BRST Cohomology and Anomaly Polynomials

    hep-th 2026-06 unverdicted novelty 6.0

    Develops Čech-de Rham bicomplex from gerbe data for BV-BRST cohomology of U(1) 2-form gauge theories and anomaly polynomials of 1-form symmetries.

  4. On Quantum Aspects of 1-Form Symmetries I: BV-BRST Cohomology and Anomaly Polynomials

    hep-th 2026-06 unverdicted novelty 5.0

    Constructs Čech-de Rham bicomplex from gerbe data for BV-BRST complex and anomaly descent of U(1) 1-form symmetries in Maxwell theory.
