Given a di erentially at system of ODEs, at outputs that depend only on original variables but not on their derivatives are called zero-at outputs and systems possessing such outputs are called zero-at. In this paper we present a theory of zero-atness for a system of two one-forms in arbitrary numbe
We consider nonlinear elliptic differential equations of second order in two variables F (x, y, z(x, y), z x (x, y), . . . , z yy (x, y)) = 0, (x, y) β β R 2 . Supposing analyticity of F , we prove analyticity of the real solution z = z(x, y) in the open set . Furthermore, we show that z may be cont
