Abstract

In view of recent work on non commutative geometry involving various Fréchet spaces (resp. algebras), isomorphic to the space s of rapidly decreasing sequences, and their tensor algebras it appears to be of interest to determine the isomorphy type of the tensor algebra T(s) of s. We show that T(s)  s and that, moreover, for any complemented subspace E of s with dim E  2 we have T(s)  s. This, in particular, includes all nuclear power series spaces of infinite type as e.g. the space of entire holomorphic functions in any finite dimension.
