The group reduction for bounded cosine functions on UMD spaces

Functional Analysis 2007-09-19 v2

Abstract

It is shown that if A generates a bounded cosine operator function on a UMD space X, then i(-A)^{1/2} generates a bounded C_0-group. The proof uses a transference principle for cosine functions.
