The dynamics of a time delay stage-structured prey-predator model is investigated. Firstly, through the analysis of the eigenvalues, the effect of time delay on the stability of the positive equilibrium and the existence of Hopf bifurcation are obtained. Further, the stability an...

The vector space of the multi-indexed sequences over a field and the vector space of the sequences with finite support are dual to each other, with respect to an appropriate scalar product. It follows that the polynomial operator in the shift which U. Oberst and J. C. Willems hav...

An attempt is made to approach the irreducible representations of the exceptional Lie groups G2 and F4 by symmetrization of some defining representations by means of Young tableaux, procedure that works rather well for most of the classical groups. For G2 the program is completel...

The aim of this paper is to solve the tenth and twelfth order linear and nonlinear boundary value problems numerically by the Galerkin weighted residual technique with two point boundary conditions. The well known Bernstein polynomials are exploited as basis functions in the tech...

Originating from the convolution sum for n 2 N by Kim’s result, we try to induce the convolution sum formulae as therefore we obtain the desired results. Moreover we construct some various convolution sums and obtain their formulae

In this paper, the concept of countably C-approximating posets is introduced. Properties and characterizations of countably C-approximating posets are presented. Main results are: (1) the lattice of all σ-Scott-closed subsets for any poset is countably C-approximating; (2) a comp...
