The Harnack inequality for (elliptic)Q-minima then is proved in [2]. Wieser extended the notion of Q-minima to the parabolic case, and obtained the Hlder continuity. In this note, under those conditions, by which the Hlder continuity of the parabolic Q-minima was obtained in [ 3], we prove that the Harnack inequalities hold for Q-minima.展开更多

In the first part, we are concerned with the locally Hlder continuity of quasi-minima of the following integral functional ∫Ωf(x, u, Du)dx, (1) where Ω is an open subset of Euclidean N-space (N ≥ 3), u:Ω → R,the Carath′eodory function f satisfies the critical Sobolev exponent growth condition |Du|^p* |u|^p*-a(x) ≤ f(x,u,Du) ≤ L(|Du|^p+|u|^p* + a(x)), (2) where L≥1, 1pN,p^* = Np/N-p , and a(x) is a nonnegative function that lies in a suitable Lp space. In the second part, we study the locally Hlder continuity of ω-minima of (1). Our method is to compare the ω-minima of (1) with the minima of corresponding function determined by its critical Sobolev exponent growth condition. Finally, we obtain the regularity by Ekeland’s variational principal.展开更多
