Radial Symmetry of Minimizers for p(x)-Laplacian Integral Functionals
Fan Xian · Journal of Gansu Education College · 2000
It is proved that the unconstrained minimizers for the p(x)-Laplacian integral functionals satisfying some natural conditions must possess radial symmetry.A corresponding result in the case of p=2 obtained by O. Lopes is generalized.
