摘要
This paper is concerned with nonlinear degenerate parabolic equations of the form . Under appropriate boundary conditions it is shown that there exists a weak solution u . Some of the main results of the paper are that u ⩾ 0 if u 0 ⩾ 0, and that the support of u (·, t ) (when u 0 ⩾ 0) increases with t (for the last property we require that n ⩾ 2 and m = 1).
