Factor-Group-Generated Polar Spaces and (Multi-)Qudits

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
Recently, a number of interesting relations have been discovered between generalised Pauli/Dirac groups and certain finite geometries. Here, we succeeded in finding a general unifying framework for all these relations.

Global behavior of the solutions of some difference equations

open access: yesAdvances in Difference Equations, 2011
In this article we study the difference equation x n + 1 = a x n - l x n - k b x n - p - c x n - q , n = 0 , 1 , … , where the initial conditions x-r, x-r+1, x-r+2,..., x0 are arbitrary positive real ...

Solution to a system of equations modelling compressible fluid flow with capillary stress effects

open access: yesElectronic Journal of Differential Equations, 2010
We study the initial-value problem for a system of nonlinear equations that models the flow of a compressible fluid with capillary stress effects. The system includes hyperbolic equations for the density and for the velocity, and an algebraic equation

Positive and Dead-Core Solutions of Two-Point Singular Boundary Value Problems with ϕ-Laplacian

open access: yesAdvances in Difference Equations, 2010
The paper discusses the existence of positive solutions, dead-core solutions, and pseudo-dead-core solutions of the singular problem (ϕ(u′))′=λf(t,u,u′), u(0)-αu′(0)=A, u(T)+βu′(0)+&#
