Comparison theorems for elliptic differential systems

Charles Andrew Swanson

Vol. 33 (1970), No. 2, 445–450
Abstract

Comparison theorems of Sturm’s type are established for systems of quasilinear elliptic partial differential equations. Specialization to ordinary linear systems and to single partial differential inequalities yields sharper results than those previously available.
