Characterizing the Strong Maximum Principle

In this paper we characterize the degenerate elliptic equations F(Du) = 0 whose subsolutions (F(Du) ≥ 0) satisfy the strong maximum principle. We introduce an easily computed function f on (0,∞) which is determined by F, and we show that the strong maximum principle holds depending on whether ∫ 0+ dy f(y) is infinite or finite. This complements our previous work characterizing when the (ordinar...

The Strong Maximum Principle on Infinite Networks

We study the strong maximum principle for the heat equation associated with the Dirichlet form on an infinite network. We prove that the strong maximum principle is equivalent to the underlying graph being connected after deletion of the nodes with infinite degree. Using this result, we prove that the multiplicity of the eigenvalue 0 of a generalization of the Laplace matrix equals the number o...

A Strong Maximum Principle for Quasilinear Parabolic Differential Inequalities

A maximum principle for C1 solutions of quasilinear parabolic differential inequalities which retains the strong conclusion of Nirenberg's well-known result [2] is established. The case of strongly differentiable solutions rather than of class C1 is also discussed.

The Anthropic Principle Revisited

The usage of the anthropic principle in modern cosmology is reviewed. It is argued that its recent use to explain the observed values of cosmological parameters as most probable values for an ensemble of universes, is not justified. However, the anthropic principle can be invoked to argue that a vast number of universes must exist, in which the cosmological parameters and constants of nature ta...
