Abstract: We consider nonlinear partial differential equations with several Fuchsian variables of type $ a(t,D_{t}) u(t,x) = f(t,x,Du(t,x))$, where $ a(t,D_{t})$ is a Fuchsian principal part of weight zero. We prove existence and uniqueness of a global solution to this problem in the space of holomorphic functions with respect to the Fuchsian variable $ t$ and in Gevrey spaces with respect to the other variable $ x$. The method of proof is based on the application of the fixed point theorem in some Banach algebras defined by majorant functions that are suitable to this kind of equation.
