Operators on the space of bounded strongly measurable functions [PDF]
, 2012 Let L(X,Y) stand for the space of all bounded linear operators between real Banach spaces (X,‖⋅‖X) and (Y,‖⋅‖Y), and let Σ be a σ-algebra of subsets of a non-empty set Ω.

Topological Properties of the Complex Vector Lattice of Bounded Measurable Functions
Journal of Function Spaces, Volume 2013, Issue 1, 2013., 2013 Let Σ be a σ‐algebra of subsets of a nonempty set Ω. Let B(Σ) be the complex vector lattice of bounded Σ‐measurable complex‐valued functions on Ω and let ca(Σ) be the Banach space of all bounded countably additive complex‐valued measures on Ω. We study locally solid topologies on B(Σ).

Fixed‐Point Theory on a Frechet Topological Vector Space
International Journal of Mathematics and Mathematical Sciences, Volume 2011, Issue 1, 2011., 2011 We establish some versions of fixed‐point theorem in a Frechet topological vector space E. The main result is that every map A = BC (where B is a continuous map and C is a continuous linear weakly compact operator) from a closed convex subset of a Frechet topological vector space having the Dunford‐Pettis property into itself has fixed‐point.

Spectral properties of a non-compact operator in ecology [PDF]
, 2021 Ecologists have recently used integral projection models (IPMs) to study fish and other animals which continue to grow throughout their lives. Such animals cannot shrink, since they have bony skeletons; a mathematical consequence of this is that the ...

On the Adjoint of a Strongly Continuous Semigroup
Abstract and Applied Analysis, Volume 2008, Issue 1, 2008., 2008 Using some techniques from vector integration, we prove the weak measurability of the adjoint of strongly continuous semigroups which factor through Banach spaces without isomorphic copy of l1; we also prove the strong continuity away from zero of the adjoint if the semigroup factors through Grothendieck spaces.

Weakly almost periodic functions, model-theoretic stability, and minimality of topological groups [PDF]
, 2015 We investigate the automorphism groups of $\aleph\_0$-categorical structures and prove that they are exactly the Roelcke precompact Polish groups. We show that the theory of a structure is stable if and only if every Roelcke uniformly continuous function

Stochastic homogenization of Hamilton--Jacobi--Bellman equations on continuum percolation clusters [PDF]
, 2022 We prove homogenization properties of random Hamilton--Jacobi--Bellman (HJB) equations on continuum percolation clusters, almost surely w.r.t. the law of the environment when the origin belongs to the unbounded component in the continuum.

The τ‐fixed point property for nonexpansive mappings
Abstract and Applied Analysis, Volume 3, Issue 3-4, Page 343-362, 1998., 1998 Let X be a Banach space and τ a topology on X. We say that X has the τ‐fixed point property (τ‐FPP) if every nonexpansive mapping T defined from a bounded convex τ‐sequentially compact subset C of X into C has a fixed point. When τ satisfies certain regularity conditions, we show that normal structure assures the τ‐FPP and Goebel‐Karlovitz′s Lemma ...
