Abstract:

The paper deals with first-order matrix partial differential operators of the form L -i Summation, j 1 to j n, of L sub jxD sub j L sub 0 x where x x sub 1, ..., x sub nepsilonR superscript n, D sub j the partial dreivative with respect to j, and the L sub j x, j 0, 1, 2,..., n, are m x m matrix-valued functions of x.
