Discrete Dynamics in Nature and Society, 2015 We consider the existence and properties of the global attractor for a class of reaction-diffusion equation ∂u/∂t-Δu-u+κ(x)|u|p-2u+f(u)=0, in Rn×R+; u(x,0)=u0(x), in Rn.

Subgroups of infinite index in the modular group II [PDF]
Glasgow Mathematical Journal, 1981 Let H be a subgroup of Γ, the modular group. Let h be the number of orbits of under the action of H. In each orbit, the stabilizers are H-conjugate. Let U be the mapping z↦z + 1. Each stabilizer is Γ-conjugate to 〈Uc〉 for some non-negative integer c. The integer c is the cusp-width of the orbit.

A relation between infinite subsets and exterior center in groups
پژوهشهای ریاضی, 2022 Let G be a group. Neumann to answer a question of Paul Erdos proved that every infinite subset of G has two different comuting elements if and only if G is center-by-finite. In this paper, we deal with Erdoschr('39')s question in different aspect and we

Dynamics of inkjet printing of shear-thinning liquids [PDF]
International Journal of Fluid EngineeringWe investigate the drop formation dynamics of shear-thinning liquids from a drop-on-demand piezoelectric inkjet printhead numerically using the volume-of-fluid (VOF) method.

Subgroups of small Index in infinite Symmetric Groups
Bulletin of the London Mathematical Society, 1986 Let \(\Omega\) be an infinite set having cardinality \(n:=| \Omega |\), and let \(S:=Sym(\Omega)\) be its symmetric group having then cardinality \(2^ n\). Moreover, let G be a subgroup of S and let \(S_{\{\Delta \}}\) or \(G_{\{\Delta \}}\) be the setwise stabilizer of \(\Delta\) in S or in G, respectively, for each subset \(\Delta\subseteq \Omega ...

On Topological Indices of OT [m, n] Octagonal Tillings and TiO2 Nanotubes
Acta Chimica Slovenica, 2019 Some well defined connectivity topological indices are Randic index, atom-bond connectivity index, geometric-arithmetic index and Shigehalli & Kanabur indices, brought into light by M. Randic, Estrada et al, Vukicevic et al and V. S. Shigehalli, in their

The cover-index of infinite graphs
Aequationes Mathematicae, 1980 We show that the cover-index of an infinite graph can be expressed in terms of colouring properties of its finite subgraphs when the minimum degree of the graph is finite. We prove that every simple graph with infinite minimum degreeδ contains a tree which is regular of degreeδ and use this to prove that every graph with minimum degreeδ can be ...
