Frechet areas were studied because the days of Banach. those areas, their inductive limits and their duals performed a popular function within the improvement of the speculation of in the neighborhood convex areas. they are also average instruments in lots of parts of genuine and intricate research. The pioneering paintings of Grothendieck within the fifties has been one of many very important assets of proposal for learn within the conception of Frechet areas. A constitution conception of nuclear Frechet areas emerged and a few vital questions posed by means of Grothendieck have been settled within the seventies. particularly, subspaces and quotient areas of reliable nuclear strength sequence areas have been thoroughly characterised. within the final years it has turn into more and more transparent that the equipment utilized in the constitution concept of nuclear Frechet areas truly supply new perception to linear difficulties in assorted branches of research and bring about strategies of a few classical difficulties. The unifying subject at our Workshop was once the hot advancements within the thought of the projective restrict functor. this can be applicable end result of the very important function this concept had within the contemporary examine. the most result of the constitution idea of nuclear Frechet areas could be formulated and proved in the framework of this conception. a tremendous sector of program of the speculation of the projective restrict functor is to make a decision while a linear operator is surjective and, whether it is, to figure out even if it has a continuing correct inverse.

1 was announced in [MTV]. §2. Characterization for V' (n). It is possible to give a simple characterization of when there exists a right inverse for P(D) on V' (n) in terms of supports of solutions of the equation P(D)u = f in case n is an arbitrary open set in R N. It is convenient to introduce the following notation. First, for e > 0 let and Further, let N(n) = {Jl E V'(n) I P(D)Jl = O} denote the null space of P(D). In the following theorem, we consider V' (n) as being equipped with its usual strong topology, and denote this space V~(n).

Let aj;k,m = aj,k for all j, k, m, where (aj,k)j,k is the matrix of a non-distinguished Kothe space (see Kothe [6, p. 438]). Notice that in this case Projl X = 0, however X* # x{,. 23 For 1 ~ p < +00 the Bk,m are closed in Xk, hence the Bk,m are a fundamental system of bounded sets in Xk (see [6, p. 406 fJ). For p = +00 this needs not to be the case (see [6, p. 437 fJ). To avoid these difficulties we assume for p = 1,00 Vk, m 3M : a)"km -'-'- = 0 . ) a;;k,M li~ --Xk Hence we are in the (DFS)-case , so X* = X{, (see §3) and Bk,m are a fundamental system of bounded sets in Xk.
