Universidad de Zaragoza (orcid)0000-0003-2453-7841 Hermite expansions of C0-groups and cosine functions 2015 In this paper we introduce vector-valued Hermite expansions to approximate one-parameter operator families such as -groups and cosine functions. In both cases we estimate the rate of convergence of these Hermite expansions to the related family and compare to other already known approximations. Finally, we illustrate our results with particular examples of -groups and cosine functions and their Hermite expansions.
