Uniform Convergence and Spectra of Operators in a Class of Fréchet Spaces [PDF]
Abstract and Applied Analysis, 2014 Well-known Banach space results (e.g., due to J. Koliha and Y. Katznelson/L. Tzafriri), which relate conditions on the spectrum of a bounded operator T to the operator norm convergence of certain sequences of operators generated by T, are extended to ...

Cosine families of operators in a class of Fréchet spaces
Proyecciones (Antofagasta), 2018 M. sova [10] proved that the infinitesimal generator of all uniformly continuous cosine family, of operators in Banach space, is a bounded operator. We show by counter-example that the result mentioned above is not true in general on Fréchet spaces, and ...

F-HYPERCYCLIC OPERATORS ON FRÉCHET SPACES
Publications de l'Institut Math?matique (Belgrade), 2018 We investigate F-hypercyclicity of linear, not necessarily continuous, operators on Frechet spaces. The notion of lower (mn)-hypercyclicity seems to be new and not considered elsewhere even for linear continuous operators acting on Frechet spaces.

On a System of Volterra Type Hadamard Fractional Integral Equations in Fréchet Spaces [PDF]
Discrete Dynamics in Nature and Society, 2018 In this article we present some results concerning the existence of solutions for a system of Hadamard integral equations. Our investigation is conducted with an application of an extension of the fixed point theorem of Burton-Kirk in Fréchet spaces.

Cubo (Temuco), 2023 In this paper, we investigate existence of mild solutions to a non-instantaneous integrodifferential equation via resolvent operators in the sense of Grimmer in Fréchet spaces. Utilizing the technique of measures of noncompactness in conjunction with the

Extending Whitney's extension theorem: nonlinear function spaces [PDF]
, 2020 We consider a global, nonlinear version of the Whitney extension problem for manifold-valued smooth functions on closed domains $C$, with non-smooth boundary, in possibly non-compact manifolds.

Some results on asymptotically normable Frechet spaces
Bibechana, 2010 In this paper, it is shown that the asymptotically normable spaces are the smallest class of Frechet spaces which contains the nuclear Kothe spaces with continuous norm, the Banach spaces and is closed under e-tensor products and sub-spaces.

AIMS Mathematics, 2020 This paper deals with the existence of mild solutions for non-linear fractional integrodifferential equations with state-dependent nonlocal conditions. The technique used is a generalization of the classical Darbo fixed point theorem for Frechet spaces ...
