[Abstract]:In this paper, by using the comparison principle and the upper and lower solution methods, we study the initial-boundary value problem of P-Laplacian equation as follows: where p1 is a given constant, ". It is a bounded region with smooth boundary in R _ n and is a nonnegative function. The quenching and non-extinguishing properties of the solution of the equation are obtained under the condition of initial value and zero boundary value. The initial-boundary value problem of the following heat conduction equations is also studied: where mtn 鈮，
