Resumen de A quantitative version of Trotter's approximation theorem

Elisabetta M. Mangino, Ioan Rasa

• A quantitative version, based on modified K-functionals, of the classical Trotter's theorem concerning the approximation of C0-semigroups is presented. The result is applied to the study of the degree of convergence of the iterated Bernstein operators on the N-dimensional simplex to their limiting semigroup.
