THE SYMMETRY OF POSITIVE SOLUTIONS OF PERIODIC-PARABOLIC PROBLEMS

[摘要] In this paper, we generalized a result of Gidas, Ni and Nirenberg (1979) on the forced symmetry of positive solutions of nonlinear elliptic problems to the periodic (in time) problem for nonlinear parabolic equations with Dirichlet boundary conditions.
