Abstract: The purpose of this paper is to give sharp error estimates for regularized versions of

-stable rational approximations of

-regularized semigroups such as the Backward Euler and Crank-Nicolson scheme among others. The main tools used are those developed by P. Brenner and V. Thomée for strongly continuous semigroups together with a regularized version of the Hille-Phillips functional calculus.
