RT Journal Article T1 A gradient estimate to a degenerate parabolic equation with a singular absorption term: The global quenching phenomena A1 Dao, N. A. A1 Díaz Díaz, Jesús Ildefonso AB We prove global existence of nonnegative solutions to the one dimensional degenerate parabolic problems containing a singular term. We also show the global quenching phenomena for L1 initial datums. Moreover, the free boundary problem is considered in this paper.
