Gerstenhaber brackets on Hochschild cohomology of general twisted tensor products (1909.02181v5)
Published 5 Sep 2019 in math.RA and math.RT
Abstract: We present techniques for computing Gerstenhaber brackets on Hochschild cohomology of general twisted tensor product algebras. These techniques involve twisted tensor product resolutions and are based on recent results on Gerstenhaber brackets expressed on arbitrary bimodule resolutions.
