Convergence Rates for the Trotter Splitting for Unbounded Operators

Simon Becker, Niklas Galke, Robert Salzmann +1

We study convergence rates of the Trotter splitting $e^{A+L}={\lim }_{n\to \infty }(e^{L/n}{e}^{A/n}{)}^n$ in the strong operator topology. In the first part, we use complex interpola…
