Discrete Hessian complexes in three dimensions (2012.10914v1)
Published 20 Dec 2020 in gr-qc, cs.NA, and math.NA
Abstract: One conforming and one non-conforming virtual element Hessian complexes on tetrahedral grids are constructed based on decompositions of polynomial tensor space. They are applied to discretize the linearized time-independent Einstein-Bianchi system.
