Non-Admissible Data for Differential Equations With Constant Coefficients

  • Fritz John
Part of the Contemporary Mathematicians book series (CM)


The general differential equation of order m with constant coefficients for a function u of the real independent variables x 1,…,x n , t can be written in the form
$$P\left( {\xi ,\tau } \right)u\left( {x,t} \right) = 0$$
