Picone's identity and the moving plane procedure

Electron. J. Differ. Equ. 1995(14), Paper 14, 13 p. (1995)

Summary

Summary: Positive solutions of a class of nonlinear elliptic partial differential equations are shown to be symmetric by means of the moving plane argument coupled with Spectral Theory results and Picone's Identity. The method adapts easily to situations where the moving plane procedure gives rise to variational problems with positive eigenfunctions.
