**Certain pl(m,n)-Kummer Matrix Function of Two Complex Variables under Differential Operator** ()

The main aim of this paper is to define and study of a new matrix functions, say, the *pl*(*m*,*n*)-Kummer matrix function of two complex variables. The radius of regularity, recurrence relation and several new results on this function are established when the positive integers *p* is greater than one. Finally, we obtain a higher order partial differential equation satisfied by the *pl*(*m*,*n*)-Kummer matrix function and some special properties.
