The Adjoint Problem Of A Modified Sturm-Liouville Boundary Value Problem
( Qatar University , 1993 , Article)The authors give the solutions of the eigenvalue equation that is associated with a modified Stum-Liouille problem. The discrete specturm and hence the resolvent will be obtained by means of different types of solutions ... -
On an inverse scattering problem with a discontinuous coefficient On the whole line
( Qatar University , 1994 , Article)This paper is devoted to study the inverse scattering problem of a generalized Sturm-Liouville equation on the whole line.The solutions of the considered problem and their asymptotic behaviour are presented.The expansion ... -
On the direct problem and scattering data for a singular system of differential Equations with discontinuous coefficients
( Qatar University , 1996 , Article)A system of Sturm-Liouiville differential equations of order n with a density matrix function is considered. The direct problem of the considered system is studied and hence the scattering data of the problem is obtained.
