报告摘要：Due to the dissipative structure of regularity-loss, extra higher regularity is usually imposed to obtain the optimal decay rates of classical solutions to dissipative systems. Our recent work is to seek the lowest regularity index for the optimal decay rate of L^1-L^2 type. To this end, a notion of minimal decay regularity for dissipative systems of regularity-loss is firstly proposed. We develop a new time-decay estimate of L^p-L^q-L^r type by using the low-frequency and high-frequency analysis in Fourier spaces. As a direct application, for compressible Euler-Maxwell equations with the weaker dissipative mechanism, it is shown that the minimal decay regularity coincides with the critical regularity for global classical solutions.
