摘要: 考慮一類具強吸收項的擬線性拋物方程Cauchy問題, 由于強吸收項的作用, 該問題的解可以在有限時刻具有緊支集和發生熄滅. 首先, 利用比較原理, 通過構造合適的上解證明

該問題的解在某個時刻后具有一致的緊支集, 甚至還可以在任意正時刻后都具有一致的緊支集. 其次, 在一定條件下, 利用該問題的解在不同時刻的L1范數估計, 證明其在有限時刻發生熄滅.

關鍵詞: 擬線性拋物方程; 強吸收項; 緊支集; 熄滅

Compact Supports and Extinction of Solutions to QuasilinearParabolic Equations with Strong Absorption Terms

LI Yanan, WANG Chunpeng

Abstract: We considered" the Cauchy problem of a class of quasilinear parabolic equations with strong absorption terms. Due to the effect of the strong absorption term,

the solution to the problem could" possess compact support and extinguish" at a finite time. Firstly, by using" the comparison principle and constructing suitable supersolutions,

it was proven that the solution possessed a uniform compact support after a certain time and even after any positive time. Secondly, under some conditions, it was proven that the solution extinguished at a finite time

by using the L1 norm estimates of the solution to the problem at different times.

Keywords: quasilinear parabolic equation; strong absorption term; compact support; extinction
