In this article,we study on the existence of solution for a singularities of a system of nonlinear fractional differential equations(FDE).We construct a formal
This paper is sequel to the authors paper [18]. By using the generalized Burchnall-Chaundy operator method, the authors are aiming at deriving certain decomposi
Using the Gegenbauer polynomials and the zonal harmonics functions we give some representation formula of the Green function in the annulus. We apply this resul
On Copositive In this paper the author writes a simple characterization for the best copositiveapproximation to elements of C(Q) by elements of finite dimensional
