Weakly Symmetric Functions on Spaces of Lebesgue Integrable Functions
Carpathian Mathematical Publications, 2022 In this work, we present the notion of a weakly symmetric function. We show that the subset of all weakly symmetric elements of an arbitrary vector space of functions is a vector space.

Weakly Ricci-Symmetric Space-Times and f (R,G) Gravity
MathematicsIn the present article, we classify conformally flat weakly Ricci-symmetric space-times and obtain that they represent Robertson–Walker space-times. Furthermore, we provethat a Ricci-recurrent weakly Ricci-symmetric space-time is static and a Ricci-semi ...

SymmetryWe study the space of continuous linear functionals approximated by weakly symmetric continuous linear functionals on the complex Banach space ℓ1 of all absolutely summing complex sequences. We construct the sequence of groups of symmetries on ℓ1, obtain the structure of corresponding weakly symmetric continuous linear functionals, find the completion ...

A New Class of Weakly Symmetric Spaces
Rocky Mountain Journal of Mathematics, 1999 A Riemannian manifold \(M\) is called weakly symmetric if any two points \(x,y \in M\) can be interchanged by an isometry. The authors prove that a simply connected Riemannian manifold \(M\) is weakly symmetric if it admits a complete unit Killing vector field \(X\) such that the reflections with respect to the flow lines of \(X\) can be extended to ...

New Examples of Weakly Symmetric Spaces
Monatshefte Fur Mathematik, 1998 A weakly symmetric space has been defined first by A. Selberg. According to an alternative definition, this is a Riemannian manifold such that, for every pair of points \(p\) and \(q\), there exists an isometry of this manifold interchanging \(p\) and \(q\).

Algebras of Weakly Symmetric Functions on Spaces of Lebesgue Measurable Functions
Carpathian Mathematical Publications, 2023 In this work, we investigate algebras of block-symmetric and weakly symmetric polynomials and analytic functions on complex Banach spaces of Lebesgue measurable functions, for which the $p$th power of the absolute value is Lebesgue integrable, where $p\in[1,+\infty),$ and Lebesgue measurable essentially bounded functions on $[0,1].$ We construct ...

Automorphism groups of some families of bipartite graphs
Electronic Journal of Graph Theory and Applications, 2021 This paper discusses the automorphism group of a class of weakly semiregular bipartite graphs and its subclass called WSBEND graphs. It also tries to analyse the automorphism group of the SM sum graphs and SM balancing graphs.
