Qy. Dai et Yg. Gu, A SHORT NOTE ON QUENCHING PHENOMENA FOR SEMILINEAR PARABOLIC EQUATIONS, Journal of differential equations, 137(2), 1997, pp. 240-250
In this paper, we investigate initial-boundary value problems for semi
linear parabolic differential equations with singular term. A criterio
n for the appearance of quencing phenomena of classical solution to th
e above problems on a bounded domain is given and a global existence a
nd nonexistence results of the above problems on unbounded domains are
obtained. (C) 1997 Academic Press.
