摘要:We present some recent advances on global existence of strong solutions to reaction-diffusion systems with mass dissipation. These systems typically arise from chemical reactions where spatial diffusion is also present. Under the mass action kinetics, the nonlinearities are usually of polynomial type with arbitrary high orders. This fact makes the global existence of solutions challenging, while the local existence, on the other hand, is classical. It's worth also to mention that the diffculties seem to increase as the spatial dimension n is bigger.

In this talk, we show global existence and uniform-in-time bounds of strong solutions for reaction-diffusion systems with mass dissipation in the following cases: The nonlinearities are at most (slightly super-) quadratic, for all n>=1; The diffusion coefficients are either close to each other, or large enough, for all n>=1; The nonli- nearities satisfy a quadratic intermediate sum condition, for n<=2. This talk is based on joint works with Brian Cupps (Washington), Klemens Fellner (Graz) and Jeff Morgan (Houston).
