“…Apart from dual, triple series solutions, Dwivedi and Trivedi have worked on quadruple series equations which are very useful for four part boundary value problems. Awasthi and Rachna [7] also worked on variety of integral and series equations to solve cracks. In view of importance of quadruple series solutions, the following paper considers the quadruple series equations involving the product of 'r' generalized Bateman K -functions.…”
