A Note on Anti-De Sitter Spaces as G-Manifolds

International Journal of Mathematics and Mathematical Sciences
We classify the orbits and orbit spaces of cohomogeneity two isometric actions of compact and connected Lie groups on anti-de Sitter spaces. We also give a more simple proof for the previously proven theorem about the similar classifications for ...

Asymptotic Behavior of Weak Solutions of Nonisothermal Flow of Herschel–Bulkley Fluid to Free Boundary

Discrete Dynamics in Nature and Society, 2022
In this manuscript, the behavior of a Herschel–Bulkley fluid has been discussed in a thin layer in ℝ3 associated with a nonlinear stationary, nonisothermal, and incompressible model.

Existence of a mountain pass solution for a nonlocal fractional ( p , q ) $(p, q)$ -Laplacian problem

Boundary Value Problems, 2020
Here, a nonlocal nonlinear operator known as the fractional ( p , q ) $(p,q)$ -Laplacian is considered. The existence of a mountain pass solution is proved via critical point theory and variational methods.

Composition-Differentiation Operators on Derivative Hardy Spaces

Journal of Mathematics
We first explore conditions under which every weighted composition-differentiation operator on the Hardy space H1D is completely continuous. We then discuss necessary and sufficient conditions for these operators to be Hilbert–Schmidt on the derivative ...

Resolving Edge Colorings: Exact Results and a Tabu Search Heuristic

International Journal of Mathematics and Mathematical Sciences
This study presents new results on resolving edge colorings in graphs, a concept introduced by V. Saenpholphat and P. Zhang in 2003. We determine the resolving edge chromatic number for several well-known families of graphs, including complete graphs ...

Generalized Lorentzian Ricci solitons on 3-dimensional Lie groups associated to the Bott Connection [PDF]

AUT Journal of Mathematics and Computing
In this paper, we investigate which one of the non-isometric left-invariant Lorentz metrics $g$ on $3$-dimensional Lie groups satisfies the generalized Ricci soliton equation $a{\rm Ric}^B [g] + \dfrac{b}{2}{\cal L}_{ X}^B g +cX^\flat\otimes X^\flat ...

f-Fixed Points of Isotone f-Derivations on a Lattice

Discussiones Mathematicae - General Algebra and Applications, 2019
In a recent paper, Çeven and Öztürk have generalized the notion of derivation on a lattice to f-derivation, where f is a given function of that lattice into itself.

Computation of Wiener and Wiener Polarity Indices of a Class of Nanostar Dendrimer Using Vertex Weighted Graphs

Journal of Mathematics
Nanostar dendrimers are tree-like nanostructures with a well-defined, symmetrical architecture. They are built in a step-by-step, controlled synthesis process, with each layer or generation building on the previous one.
