A comparison principle for minimizers

Comptes Rendus de l'Académie des Sciences - Series I - Mathematics, 2000
The authors present conditions for the validity of a comparison principle, which do not require the validity of the Euler-Lagrange equation. They derive a weak maximum principle even for some degenerate elliptic equation and prove Lipschitz continuity of minimizers under a variant of the bounded slope condition.

A Comparison Principle and the Lipschitz Continuity for Minimizers

, 2001
The authors are interested in the minimizing problem \(\int_{\Omega} L(x,u,\nabla u) \,dx \to \min\) on \(\bar{u}+W^{1,q}_{0}(\Omega)\), \(L(x,z,p)\): \(\Omega \times \mathbb{R}\times \mathbb{R}^{n}\to \mathbb{R}\). Imposing only very weak assumptions (for instance no growth conditions and no differentiability properties on \(L\) are imposed), they ...

A Comparison of anonymization protection principles

2012 IEEE 13th International Conference on Information Reuse & Integration (IRI), 2012
We do a survey of some of the most important principles of anonymization present in the literature. We identify different kinds of attacks that can be thrown against an anonymized dataset and give formulas for the maximum probability of success for each.

On comparison principles for the periodic Hill's equation

Journal of the London Mathematical Society, 2012
In this work we make an exhaustive study of the properties of the Green’s function related to the periodic boundary value problem La x ≡ x′′ + a(t) x = 0, x(0) = x(T ), x′(0) = x′(T ), with a sign-changing potential a(t). Moreover, we obtain new explicit criteria that ensures the maximum or antimaximum principle holds for this equation.

Principles of biological comparison.

Acta morphologica Neerlando-Scandinavica, 1989
The problems of comparative analyses in biology have been discussed, showing that a single comparative method does not exist. Several principles of comparison are elucidated, which include that comparisons do not have to possess a phylogenetic basis, can be horizontal or vertical, and can be genetic or nongenetic.

Model abstraction and inclusion principle: a comparison

IEEE Transactions on Automatic Control, 2002
This paper discusses connections between the inclusion principle and model abstraction in large-scale hierarchical control systems. It also provides conditions for implementation of controllability and observability in linear continuous-time dynamic systems satisfying either aggregation or restriction conditions, as well as for observability ...

Maximum and Comparison Principles

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 of the Paris Principles and the International Cataloguing Principles

Cataloging & Classification Quarterly, 2009
After more than forty-five years of cataloging experience with the Paris Principles and their impact on the international sharing of bibliographic data, the process of replacing them with a wider and deeper set of International Cataloguing Principles has been completed. This article compares the scope, technological context, process of decision making,
