Abstract
New linear topological invariants are introduced and utilized to give an isomorphic classification of tensor products of the type $E_{∞}(a) ⊗̂ E'_{∞}(b)$, where $E_{∞}(a)$ is a power series space of infinite type. These invariants are modifications of those suggested earlier by Zahariuta. In particular, some new results are obtained for spaces of infinitely differentiable functions with values in a locally convex space X. These spaces coincide, up to isomorphism, with spaces L(s',X) of all continuous linear operators into X from the dual space of the space s of rapidly decreasing sequences. Most of the results given here with proofs were announced in [12].
