In this paper, we mainly make use of the concave envelope method to prove the following results: Consider the following problemwhere is a bounded and convex domain.Furthermore, we shall give Pinchingestimate for general equation and the proof of ndimensional for the Laplace equation and an application of Hamilton tensor maximum principle.
