Notes on the Chernoff Product Formula (1911.09480v1)
Published 21 Nov 2019 in math.FA
Abstract: We revise the strong convergent Chernoff product formula and extend it, in a Hilbert space, to convergence in the operator-norm topology. Main results deal with the self-adjoint Chernoff product formula. The nonself-adjoint case concerns the quasi-sectorial contractions.
