指数型反应扩散方程解的爆破剖面

Blow-up profiles of solutions for the exponential reaction-diffusion equation

Aappo Pulkkinen

摘要:

考虑一类带指数反应项的半线性反应扩散方程解的爆破问题。我们知道,某些可以继续超过爆破时间的解具有非常数自相似爆破轮廓。我们的目标是找到最终的时间爆破的轮廓,这样的解决方案。证明是基于一般的想法,使用半群估计。同样的方法也适用于功率非线性。

英文摘要:

We consider the blow-up of solutions for a semilinear reaction diffusion equation with exponential reaction term. It is know that certain solutions that can be continued beyond the blow-up time possess a nonconstant selfsimilar blow-up profile. Our aim is to find the final time blow-up profile for such solutions. The proof is based on general ideas using semigroup estimates. The same approach works also for the power nonlinearity.
