In this presented paper, we are concerned with the oscillatory behaviour of solutions of some nonlinear ordinary differential equations of second order. Primarily, we are interested in the study of equations with integrable ...

In this paper, we combine the homotopy perturbation method, Sumudu transform and He’s polynomials to obtain the approximate /exact solution of some partial differential equations of fractional order. The fractional derivative ...

In this paper, we consider singular linear systems of algebraic equations on the form We introduce formulas for the Moore- Penrose generalized inverse of depend on the ranks of , and based on the adgugate matrix. Using ...

In this paper, we investigates the relation between the ring-theoretic properties of Rand the graph-theoretic properties of G(R), where Ris a finite commutative ring with unity, and G(R) is a simple undirected graph ...

Abstract: The response of a dynamical non-linear system of two-degree-of freedom, subjected to multi excitations forces is investigated. Analysis of the amplitude and phase plane are obtained. The multiple ...
