Systems Of Nonlinear Wave Equations With Damping And Supercritical Sources, Yanqiu Guo Apr 2012

Systems Of Nonlinear Wave Equations With Damping And Supercritical Sources, Yanqiu Guo

Department of Mathematics: Dissertations, Theses, and Student Research

We consider the local and global well-posedness of the coupled nonlinear wave equations

utt – Δu + g1(ut) = f1(u, v)

vtt – Δv + g2(vt) = f2(u, v);

in a bounded domain Ω subset of the real numbers (Rn) with a nonlinear Robin boundary condition on u and a zero boundary conditions on v. The nonlinearities f1(u, v) and f2(u, v) are with supercritical exponents …
