An index formula for the degree of (S)+-mappings associated with one-dimensional p-Laplacian

Jun Kobayashi; Mitsuharu Ôtani

The topological degree for (S) + -mappings concerning a nonlinear eigenvalue problem associated with one-dimensional p -Laplacian is evaluated. The result is applied to a variational inequality, where the multiple existence of solutions is discussed.

L ∞-energy method, basic tools and usage

Mitsuharu Ôtani

A new method called “L ∞-Energy Method” is introduced. Several basic tools for this method are prepared and a couple of typical ways of usage of this method are exemplified for quasilinear parabolic equations.
