Boundedness properties in function spaces

open access: yesQuaestiones Mathematicae, 2018
Some boundedness properties of function spaces (considered as topological groups) are studied.Mathematics Subject Classification (2010): Primary: 54C35; Secondary: 54D20, 54H11.Keywords: Function spaces, ℵ0-bounded, M-bounded, H-bounded, R-bounded, σ ...

A note on bf-spaces and on the distribution of the functor of the Dieudonné completion

open access: yesTopological Algebra and its Applications, 2021
A subset B of a space X is said to be bounded (in X) if the restriction to B of every real-valued continuous function on X is bounded. A real-valued function on X is called bf-continuous if its restriction to each bounded subset of X has a continuous ...

Separation functions and mild topologies

open access: yesAnalysis and Geometry in Metric Spaces, 2023
Given MM and NN Hausdorff topological spaces, we study topologies on the space C0(M;N){C}^{0}\left(M;\hspace{0.33em}N) of continuous maps f:M→Nf:M\to N. We review two classical topologies, the “strong” and the “weak” topology. We propose a definition of “

On some dense sets in the space of dynamical systems

open access: yesAdvanced Nonlinear Studies, 2023
The natural consequence of the existence of different kinds of chaos is the study of their mutual dependence and the relationship between these concepts and the entropy of systems. This observation also applies to the local approach to this issue.

A study of uniformities on the space of uniformly continuous mappings

open access: yesOpen Mathematics, 2020
New families of uniformities are introduced on UC(X,Y)UC(X,Y), the class of uniformly continuous mappings between X and Y, where (X,U)(X,{\mathcal{U}}) and (Y,V)(Y,{\mathcal{V}}) are uniform spaces.

Dual uniformities in function spaces over uniform continuity

open access: yesOpen Mathematics, 2022
The notion of dual uniformity is introduced on UC(Y,Z)UC(Y,Z), the uniform space of uniformly continuous mappings between YY and ZZ, where (Y,V)(Y,{\mathcal{V}}) and (Z,U)(Z,{\mathcal{U}}) are two uniform spaces.

On the Hochschild cohomology of a map between commutative differential graded algebras

open access: yesTopological Algebra and its Applications, 2022
We consider a surjective morphism between commutative differential graded algebras ϕ: (∧V, d) → (B, d), where V is finite dimensional, and (B, d) is a module over ∧V via the mapping ϕ.

Averaging operators and set-valued maps [PDF]

open access: yes, 2014
MSC 2010: 54C35, 54C60.We investigate maps admitting, in general, non-linear averaging operators. Characterizations of maps admitting a normed, weakly additive averaging operator which preserves max (resp., min) and weakly preserves min (resp., max) is ...

Some applications of exponentially separable spaces

open access: yes, 2021
We prove that any finite product of functionally countable spaces is functionally countable if it has the Lindelöf property. In particular, any nite product of functionally countable Lindelof Σ-spaces is functionally countable.
