Frechet-Urysohn property of quasicontinuous functions
, 2023 The aim of this paper is to study the Frechet-Urysohn property of the space $Q_p(X,\mathbb{R})$ of real-valued quasicontinuous functions, defined on a Hausdorff space $X$, endowed with the pointwise convergence topology.

Operators between different weighted Frechet and (LB)-spaces of analytic functions
, 2021 We study some classical operators defined on the weighted Bergman Frechet space A(alpha+)(p) (resp. weighted Bergman (LB)-space A(alpha-)(p)) arising as the projective limit (resp.

The compact approximation property for spaces of holomorphic mappings on Frechet spaces
, 2021 In this paper, the compact approximation property on Frechet spaces is characterized in terms of holomorphic mappings. We show that a Frechet space E has the compact approximation property if and only if every holomorphic mapping on a balanced open ...

The existence of a factorized unbounded operator between Frechet spaces [PDF]
, 2020 For locally convex spaces E and F, the continuous linear map T : E -> F is called bounded if there is a zero neighborhood U of E such that T(U) is bounded in F. Our main result is that the existence of an unbounded operator T between Frechet spaces E and
