Web3.1 Moser iteration and estimates The goal of this section is to establish Moser’s result [5] on general Harnack inequalities. We will ﬁrst prove two more general theorems (Theorems 1 and 2) from which we will deduce the more well-known forms of the inequalities appearing in these theorems. Let us now denote the average mean integral ﬄ by ... WebThe main idea is to replace the usual Picard iteration method with a modiﬁed Newton iteration scheme. Roughly speaking, the advantage is that, since this latter scheme is quadratic (see remark 1.2.1 and 1.3.2), the iterates shall converge to the expected solution at a super-exponential rate.

Webpendently, Nash introduced a similar techniques in 1958 [15]. Subsequently, Moser provided a new formulation of the proof in [14]. Those methods are now usually called De Giorgi-Nash-Moser techniques. The method has been extended to degenerated cases, like the p-Laplacian, rst in the elliptic case by Ladyzhenskaya and Uralt’seva [13]. Webnorms. Then, the aforementioned estimates on all the higher norms are deduced by using Moser’s iteration technique (see Subsection 3.4). The lower bound on the in mum then follows from the auxiliary assertion in Lemma 3.4. Our main result is a consequence of Lemmas 2.1 and 3.1. Acknowledgments.

WebWe introduce some suitable regularization to establish the solvability and tame estimates for the linearized problem. Combining the linear well-posedness result with a modified Nash--Moser iteration scheme, we prove the local existence and uniqueness of solutions of the nonlinear problem.

It was shown later by Moser that the result of De Giorgi and Nash can be obtained using a different formulation [31]. In the literature, this method is often called the De Giorgi-Nash-Moser theory.
