报告摘要:In this talk we introduce the Cauchy problem for a semilinear pseudo-parabolic equation with initial data non-rarefied at ∞. Our interest lies in the discussion of the effect of the non-rarefied factors on the blow-up phenomenon and the life span of the solution.

报告摘要:In this talk, we prove some boundary pointwise regularity for uniformly elliptic equations. Based on this pointwise regularity, we give a simple and direct proof of the higher regularity of free boundaries in obstacle-type problems.
