ON TWO-SIDED UNIDIRECTIONAL MEAN VALUE INEQUALITY IN A FRÉCHET SMOOTH SPACE
Ural Mathematical Journal, 2023 The paper is devoted to a new unidirectional mean value inequality for the Fréchet subdifferential of a continuous function. This mean value inequality finds an intermediate point and localizes its value both from above and from below; for this reason ...

A Second Adjoint Theorem for SL(2,R) [PDF]
, 2016 We formulate a second adjoint theorem in the context of tempered representations of real reductive groups, and prove it in the case of SL(2,R).Comment: 38 ...

Ekeland's inverse function theorem in graded Fréchet spaces revisited for multifunctions [PDF]
, 2016 In this paper, we present some inverse function theorems and implicit function theorems for set-valued mappings between Frechet spaces. The proof relies on Lebesgue's Dominated Convergence Theorem and on Ekeland's variational principle. An application to

Envelope Theorems for Non-Smooth and Non-Concave Optimization [PDF]
, 2012 We study general dynamic programming problems with continuous and discrete choices and general constraints. The value functions may have kinks arising (1) at indifference points between discrete choices and (2) at constraint boundaries.

Communications on Pure and Applied Analysis, 2019 In this paper we prove versions, in Frechet spaces, of the classical theorems related to exponential dichotomy for a sequence of continuous linear operators on Banach spaces.

Diametral dimensions of Frechet spaces [PDF]
, 2016 The diametral dimension is an important topological invariant in the category of Frechet spaces which has been used, e.g., to distinguish types of Stein manifolds.

I: Fréchet-Urysohn spaces [PDF]
Mathematica Moravica, 2016 In this paper, we introduce the concept ss-sequentially quotient mapping. Using this concept, we characterize s-Fréchet-Urysohn spaces and s-sequential spaces.

Evolution equations in Fréchet spaces
Journal of Mathematical Sciences and Modelling, 2018 This paper deals with the existence of mild solutions for a class of evolution equations. The technique used is a generalization of the classical Darbo fixed point theorem for Fr\'{e}chet spaces associated with the concept of measure of noncompactness.

Character groups of Hopf algebras as infinite-dimensional Lie groups [PDF]
, 2015 In this article character groups of Hopf algebras are studied from the perspective of infinite-dimensional Lie theory. For a graded and connected Hopf algebra we construct an infinite-dimensional Lie group structure on the character group with values in ...

Set valued integrability in non separable Fréchet spaces and applications [PDF]
, 2015 We focus on measurability and integrability for set valued functions in non-necessarily separable Fréchet spaces. We prove some properties concerning the equivalence between different classes of measurable multifunctions.
