Let โฆ1, โฆ2 be open subsets of R d 1 and R d 2 , respectively, and let A(โฆ1) denote the space of real analytic functions on โฆ1. We prove a Glaeser type theorem by characterizing when a composition operator Cฯ : Using this result we characterize when A(โฆ1) can be embedded topologically into A(โฆ2) as
