报告内容摘要：We review the proof of regularty of weak solutions for heatequations and then consider a class of ultraparabolic differential equationswith measurable coefficients and lower order terms.  It is proved that weak solutions to theequation are Holder continuous,which generalizes the classic results ofparabolic equations with general coefficients. The main observation is a weakSobolev inequality and Poincare inequality related to weak sub-solutions. Thisis a jointed work with Wang Wendong.
