內(nèi)容介紹：The presence of logarithmic nonlinear term of the form f(u)=u log(|u|) in  parabolic PDEs or Schrodinger’s equations brings about significant challenges in  both numerical discretization and analysis. The nonlinear term is  non-differentiable but Holder continuous at u=0, and the underlying energy does  not have a definite sign. Such PDEs exhibit interesting dynamics that may not  possess for general PDEs with smooth nonlinear terms. In this talk, we shall  present our recent attempts for such problems and introduce some new tools for  the analysis.
