一类具有混合边界条件的初边值问题解的Blow-up

ON BlOW-UP SOLUTIONS FOR A CLASS OF THE PROBLEMS WITH BOUNDARY CONDITIONS OF MIXED TYPE AND STARTING VALUE

利用非线性抛物型方程的极大值原理 ,讨论了一类具有混合边界条件的初边值问题的解的Blow up ,并得到了Blow up时间T的一个上界 .

Based on the extremum principle of nonlinear parabolic equations,the author considered the blow up solutions for a class of the problems with boundary conditions of mixed type and starting value,and gave a supremum of Blow up time.
