We consider a smooth, complete and non-compact Riemannian manifold $$(\mathcal {M},g)$$ of dimension $$d \ge 3$$ , we look for solutions to the semilinear elliptic equation $$\begin{aligned} -\varDelta _g w + V(\sigma ) = \alpha (\sigma f(w) \lambda \quad \hbox {in }\mathcal {M}. \end{aligned}$$ The potential $$V :\mathcal {M} \rightarrow \mathbb {R}$$ is continuous function which coercive in s...

We give a local characterization of the existence Kazhdan projections for arbitary families Banach space representations compactly generated locally compact group $G$. also define and study natural generalization Fell topology to arbitrary group. several applications in terms stability rigidity under perturbations. Among them, we show Banach-space version Delorme--Guichardet theorem stating tha...

‎a ring $r$ is strongly clean provided that every element‎ ‎in $r$ is the sum of an idempotent and a unit that commutate‎. ‎let‎ ‎$t_n(r,sigma)$ be the skew triangular matrix ring over a local‎ ‎ring $r$ where $sigma$ is an endomorphism of $r$‎. ‎we show that‎ ‎$t_2(r,sigma)$ is strongly clean if and only if for any $ain‎ ‎1+j(r)‎, ‎bin j(r)$‎, ‎$l_a-r_{sigma(b)}‎: ‎rto r$ is surjective‎. ‎furt...

‎In this paper‎, ‎algebraic investigations on sup-$Sigma$-algebras are presented‎. ‎A representation theorem for‎ ‎sup-$Sigma$-algebras in terms of nuclei and quotients is obtained‎. ‎Consequently‎, ‎the relationship between‎ ‎the congruence lattice of a sup-$Sigma$-algebra and the lattice of its nuclei is fully developed.

in this paper, we define the common minimal common neighborhooddominating signed graph (or common minimal $cn$-dominating signedgraph) of a given signed graph and offer a structuralcharacterization of common minimal $cn$-dominating signed graphs.in the sequel, we also obtained switching equivalencecharacterization: $overline{sigma} sim cmcn(sigma)$, where$overline{sigma}$ and $cmcn(sigma)$ are ...

This paper studies the structural formation of various spherically symmetric anisotropic configured stars in $f(\mathcal{R},\mathcal{T},\mathcal{Q})$ gravity under influence electromagnetic field, where $\mathcal{Q}=\mathcal{R}_{\eta\sigma}\mathcal{T}^{\eta\sigma}$. We construct modified field equations by adopting Krori-Barua metric potentials (involving unknowns ($A,B,C$)) and employ bag mode...

The equation of state provided by effective models strongly interacting matter should comply with the restrictions imposed current astrophysical observations on compact stars. Using given (axial-)vector meson extended linear sigma model, we determine mass-radius relation and study whether these are satisfied under assumption that most star is filled quark matter. We dependence parameters model.

We examine the fixed points to first-order RG flow of a nonlinear sigma model with background metric, dilaton and tachyon fields. We show that on compact target spaces, the existence of fixed points with nonzero tachyon is linked to the sign of the second derivative of the tachyon potential V ′′(T ) (this is the analogue of a result of Bourguignon for the zerotachyon case). For a tachyon potent...
