Moments problem in Frechet spaces

Mathematical Notes, 1993
The author gives solvability conditions of moment problems for an arbitrary sequence of linear continuous functionals over Fréchet spaces. As is known many theorems in analysis state the solvability conditions for numerous moment problems. The author notes that the solvability problem is equivalent to the fact that the sequence of linear functionals is

Distributional Chaoticity of C0-Semigroup on a Frechet Space

Symmetry, 2019
This paper is mainly concerned with distributional chaos and the principal measure of C 0 -semigroups on a Frechet space. New definitions of strong irregular (semi-irregular) vectors are given. It is proved that if C 0 -semigroup T

Quotient Spaces Without Bases in Nuclear Frechet Spaces

Canadian Journal of Mathematics, 1978
The first example of a nuclear Fréchet space without a basis was given by B. S. Mitiagin and N. M. Zobin [9; 10]. The question of existence of subspaces without bases in nuclear Fréchet spaces was recently settled in papers by P. Djakov and B. S. Mitiagin [2] and Ed Dubinsky [5]. In this paper we consider the analogous question for quotient spaces.

Interpolation in Separable Frechet Spaces with Applications to Spaces of Analytic Functions

Canadian Journal of Mathematics, 1975
Let E be a separable Fréchet space, and let E* be its topological dual space. We recall that a Fréchet space is, by definition, a complete metrizable locally convex topological vector space. A sequence {Ln} of continuous linear functional is said to be interpolating if for every sequence {An} of complex numbers, there exists an ƒ ∈ E such that Ln(ƒ ...

Some problems on bases in Banach and frechet spaces

Israel Journal of Mathematics, 1964
This paper is a revised version of the author’s report during the Symposium “On Series and Geometry in Linear Spaces” held at The Hebrew University of Jerusalem, March 16–24, 1964. Some problems of the existence (for a given Frechet space) of closed linear subspaces and quotient spaces with bases are discussed.

Nuclear Köthe Quotients of Frechet Spaces

1989
Throughout we let (math)(F) denote a base of neighborhoods of a locally convex space (les) F which consists of absolutely convex and closed sets. In this work every Kothe space will be assumed to admit a continuous norm.

Surface integrals in Frechet spaces

Sbornik: Mathematics, 1998
This paper is a continuation of the author's work on measure and integral theories within analysis in infinitely many dimensions. The current work treats surface integration in separable Fréchet spaces providing formulas for iterated integration, integration by parts, and Green and Gauss formulas as well. Some earlier announced results are proved.
