Fixed-Point Theory on a Frechet Topological Vector Space
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 ...

A Note on the Generalized Nonlinear Vector Variational-Like Inequality Problem
In this paper, we discuss two variants of the generalized nonlinear vector variational-like inequality problem. We provide their solutions by adopting topological approach.

On the symmetries of BF models and their relation with gravity [PDF]
The perturbative finiteness of various topological models (e.g. BF models) has its origin in an extra symmetry of the gauge-fixed action, the so-called vector supersymmetry.

The Cell Method (CM) is an algebraic numerical method based on the use of global variables: the configuration, source and energetic global variables. The configuration variables with their topological equations, on the one hand, and the source variables ...

Weak Darboux property and transitivity of linear mappings on topological vector spaces
It is shown that every linear mapping on topological vector spaces always has weak Darboux property, therefore, it is continuous if and only if it is transitive.

Menger probabilistic normed space is a category topological vector space [PDF]
In this paper, we formalize the Menger probabilistic normed space as a category in which its objects are the Menger probabilistic normed spaces and its morphisms are fuzzy continuous operators.

Nonstratifiability of topological vector spaces
A subspace \(Y\) of a topological space \(X\) is said to be \(K_{1}\) embedded if there exists a map \(\varphi :\mathcal{T}_{Y}\rightarrow \mathcal{T}_{X}\) such that for any \(U,V\in \mathcal{T}_{Y}\), if \(\varphi(U)\cap Y=U\) and \( \varphi (U)\cap \varphi (Y)\neq \emptyset\) then \(U\cap V\neq \emptyset\).

A characterization of singular endomorphisms of a barrelled Pták space
The concept of topological divisor of zero has been extended to endomorphisms of a locally convex topological vector space (LCTVS). A characterization of singular endomorphisms, similar to that of Yood [1], is obtained for endomorphisms of a barrelled ...

Photonic helicoid-like surface states in chiral metamaterials
We investigate the photonic topological phases in chiral metamaterials characterized by the magnetoelectric tensors with diagonal chirality components. The underlying medium is considered a photonic analogue of the topological semimetal featured with a ...

Non Abelian TQFT and scattering of self dual field configuration
A non-abelian topological quantum field theory describing the scattering of self-dual field configurations over topologically non-trivial Riemann surfaces, arising from the reduction of 4-dim self-dual Yang-Mills fields, is introduced.
