Operator-norm Trotter product formula on Banach spaces

Valentin A. Zagrebnov

In this paper we collect results concerning the {operator-norm} convergent {Trotter} product formula for two semigroups $\{\e^{- t A}\}_{t\geq 0}$, $\{\e^{- t B}\}_{t\geq 0}$, with…

Operator-Norm Convergence of the Trotter Product Formula on Hilbert and Banach Spaces: A Short Survey

Hagen Neidhardt, Artur Stephan, Valentin Zagrebnov

We give a review of results on the operator-norm convergence of the Trotter product formula on Hilbert and Banach spaces, which is focused on the problem of its convergence rates.…

Solution Operator for Non-Autonomous Perturbation of Gibbs Semigroup

Valentin Zagrebnov

The paper is devoted to a linear dynamics for non-autonomous perturbation of the Gibbs semigroup on a separable Hilbert space. It is shown that evolution family {U(t, s)} 0s$\…

Notes on the Chernoff Product Formula

Valentin Zagrebnov

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 Ch…

Trotter product formula and linear evolution equations on Hilbert spaces On the occasion of the 100th birthday of Tosio Kato

Hagen Neidhardt, Artur Stephan, Valentin Zagrebnov

The paper is devoted to evolution equations of the form t u(t) = --(A + B(t))u(t), t I = [0, T ], on separable Hilbert spaces where A is a non-negative s…

Trotter-Kato product formulae in Dixmier ideal

Valentin Zagrebnov

It is shown that for a certain class of the Kato functions the Trotter-Kato product formulae converge in Dixmier ideal C 1, in topology, which is defined by the 1,…
