Maximum and Comparison Principles [PDF]

, 1977
The purpose of this chapter is to provide various maximum and comparison principles for quasilinear equations which extend corresponding results in Chapter 3. We consider second order, quasilinear operators Q of the form (10.1) Qu = aij(x, u, Du)Diju + b(x, u, Du), aij = aji, where x = (x1..., xn) is contained in a domain Ω of ℝn, n ≥ 2, and, unless ...

A comparison principle for minimizers

Comptes Rendus de l'Académie des Sciences - Series I - Mathematics, 2000
We give some conditions that ensure the validity of a Comparison principle for the minimizers of integral functionals, without assuming the validity of the Euler-Lagrange equation. We deduce a weak maximum principlefor (possibly) degenerate elliptic equations and, together with a generalization of the bounded slope condition, the Lipschitz continuity ...

A Comparison Principle and the Lipschitz Continuity for Minimizers

2001
We state some recent results on the existence, uniqueness and Lipschitz regularity of the minima of the integral functional \(I(u) = \int_\Omega L (x,u,\triangledown u)dx\) for a class of integrands L(x, z, p) = f (p) + g(x,z) that are convex in (z, p) and for boundary data satisfying some barrier conditions.

Comparison of Principles and Practices of Study

The School Review, 1936
Academic achievement is largely dependent on the skill with which a person handles the techniques of study. He is compelled to use these procedures and devices if he would be efficient in scholastic endeavors whether in or out of school. His whole academic life turns about this pivotal point.
