摘要: 考虑一类具非局部边界条件抛物型方程解的爆破模式. 借助一些积分不等式, 通过适当弱化关于初值的假设条件, 得到了正解的全局爆破性质及爆破速率估计.

关键词: 全局爆破, 非局部边界条件, 爆破速率, 爆破模式

Abstract: We considered a blowup profile of solutions for a class of parabolic equations with nonlocal boundary conditions. On the basis of some integral inequalities, we suitably weakened the assumptions about the initial values, and obtained the global blowup properties and the blowup rate estimates of positive solutions.

Key words: blowup rate, blowup profile, global blowup, nonlocal boundary condition
