Title: Wave-Klein-Gordon systems in 1+2 dimensional spacetime with nonlinear interactions in divergence form
Abstract: In this talk I will regard the global wellposedness of a type of systems composed by nonlinear wave and Klein-Gordon equations in 1+2 dimensional spacetime with small and regular initial data. This type of systems can be found in differential geometry and plasma physics. The divergence structure of the Klein-Gordon-wave interaction is the key for global existence in this lower-dimensional case. These are joint works with S. Duan and W. Zhang.
