Poisson vertex algebra cohomology and differential Harrison cohomology

Published 16 Jul 2019 in math.RT, math-ph, and math.MP | (1907.06934v1)

Abstract: We construct a canonical map from the Poisson vertex algebra cohomology complex to the differential Harrison cohomology complex, which restricts to an isomorphism on the top degree. This is an important step in the computation of Poisson vertex algebra and vertex algebra cohomologies.
