Estimates for firstorder homogeneous linear characteristic problems
Abstract
An algebraic criterion that is sufficient to establish the existence of certain a priori estimates for the solution of firstorder homogeneous linear characteristic problems is derived. Estimates of such kind ensure the stability of the solutions under small variations of the data. Characteristic problems that satisfy this criterion are, in a sense, manifestly well posed.
