The BV double of a Courant algebroid (2410.20510v1)
Published 27 Oct 2024 in math.QA, hep-th, math-ph, math.DG, and math.MP
Abstract: We characterize a Courant algebroid with a Calabi-Yau structure as a homotopy BV algebra with certain properties. We explain how it fits into recent double copy constructions relating Yang-Mills homotopy algebras to the ones of Double Field Theory and Gravity.
