Around the codifferential of products of p-forms and generalized interior products (2406.02476v2)
Published 4 Jun 2024 in math-ph, gr-qc, math.DG, and math.MP
Abstract: Identities pertaining to the de Rham codifferential {\delta} in differential geometry are scattered in the literature. This article gathers such formulas involving usual differential operators (Lie derivative, Schouten-Nijenhuis bracket, ...), while adding a few new ones using a natural extension of the interior product, to provide a compact handy summary.
