On the antimaximum principle for the p-Laplacian with indefinite weight

A study of the antimaximum principle (AMP) for a class of equations involving the p-Laplacian operator with indefinite weights was presented. The AMP was extended to the case of a linear operator with weight and to the case of a nonlinear operator without weight. The uniformity of the AMP was discussed and a variational characterization for the interval of uniformity was provided.SCOPUS: ar.j
