报告内容:

    Abstract: In this talk, I will consider an Euler-Poisson system with three small parameters arising in the modeling of unmagnetized plasmas and semiconductors. For initial data close to constant equilibrium states, I will show the uniform global existence of smooth solutions

with respect to the parameters. This result implies the global-in-time convergence of the Euler-Poisson system as each of the parameters goes to zero. The proof is based on a unified energy estimate which is valid for all the parameters.
