Abstract The study of specatral properties of p artial differential equations represenes a corner stone in the study of different equations in view of its importance in various applications inadvanced studies specially i n the field of theoritical physics. These studies need in fac-b a deep understanding of various branches in mathema tics such as generalized functions, Fourier” transforms, Green’s functions and others. |
