چکیده
The norm convergence of the Trotter{Kato product formula is established with ultimate optimal error bound for the self-adjoint semigroup generated by the operator sum of two self-adjoint operators. A generalization is also given to the operator sum of several self-adjoint operators.

Results on Convergence in Norm of Exponen- tial Product Formulas and Pointwise of the Cor- responding Integral Kernels
For the last one and a half decades it has been known that the exponential product formula holds also in norm in nontrivial cases. In this note, we review the results on its convergence in norm as well as pointwise of the integral kernels in the case for Schrödinger operators, with error bounds. Optimality of the error bounds is elaborated. Mathematics Subject Classification (2000). Primary 47D...
متن کاملOn Error Estimates for the Trotter-kato Product Formula
We study the error bound in the operator norm topology for the Trotter exponential product formula as well as for its generalization a la Kato. In the frame of the abstract setting we give a simple proof of error estimates which improve some of recent results in this direction.
متن کاملTrotter Product Formula for Nonself-adjoint Gibbs Semigroups
We prove the trace-norm convergence of the Trotter product formula for nonself-adjoint Gibbs semigroups. For any m-sectorial generators A and B such that e ?tRe A is in the trace-class for t > 0, the Trotter product formula converges in the trace-norm. With smallness conditions on B with respect to A, we give error bound estimates of the convergence rate in this topology.
متن کاملA pr 2 00 4 Note on a product formula for unitary groups
For any nonnegative self-adjoint operators A and B in a separable Hilbert space, we show that the Trotter-type formula [(ei2tA/n + ei2tB/n)/2]n converges strongly in dom(A1/2) ∩ dom(B1/2) for some subsequence and for almost every t ∈ R. This result extends to the degenerate case and to Katofunctions following the method of Kato [6]. In a famous paper [6], T. Kato proved that for any nonnegative...
متن کاملStabilizations of the Trotter-kato Theorem and the Chernoff Product Formula
This paper concerns versions of the Trotter-Kato Theorem and the Chernoff Product Formula for C0-semigroups in the absence of stability. Applications to A-stable rational approximations of semigroups are presented.
