✦ Synopsis
Let X be a compact coherent real analytic subvariety of R d . It is shown that a continuous linear operator which extends real analytic functions on X to real analytic functions on R d exists if and only if X is of type PL, which means that in every point of X the local complexification satisfies Ho ¨rmander's local Phragme ´n-Lindelo ¨f condition. This is in particular true if X is a manifold.

## Abstract It is shown that for an algebraic subvariety __X__ of ℝ^__d__^ every Fréchet valued real analytic function on __X__ can be extended to a real analytic function on ℝ^__d__^ if and only if __X__ is of type (PL), i.e. all of its singularities are of a certain type. Necessity of this cond
Let Ω1, Ω2 be open subsets of R d 1 and R d 2 , respectively, and let A(Ω1) denote the space of real analytic functions on Ω1. We prove a Glaeser type theorem by characterizing when a composition operator Cϕ : Using this result we characterize when A(Ω1) can be embedded topologically into A(Ω2) as
