Global Existence of Small Amplitude Solutions for a Model Quadratic Quasilinear Coupled Wave-Klein-Gordon System in Two Space Dimension, with Mi David Pevalin the set of conceptual andThe aim of this monograph is to study the global existence of solutions to a coupled wave Klein Gordon system in space dimension two when initial data are small smooth and mildly decaying at infinity. Some physical models strictly related to general relativity have shown the importance of studying such systems but very few results are known at present in low space dimension. We study here a model two dimensional system, in which the nonlinearity
