一类quasi-linear parabolic equations极限流的唯一性

Uniqueness of limit flow for a class of quasi-linear parabolic equations

Marco Squassina, Tatsuya Watanabe

摘要:

研究了一类定义在全空间上的拟线性抛物方程的极限流的唯一性问题。更确切地说,我们将研究的条件,保证整体解决方案的衰减在无穷大时间一致,其整个轨迹接近一个单一的稳定状态,随着时间的推移到无穷大。最后,我们得到了当$λ>0$穿过分歧值$λ_0$时,对于$λφ_0$形式的初始数据,解爆破、消失或收敛到稳态的一个特征.

英文摘要:

We investigate the issue of uniqueness of the limit flow for a relevant class of quasi-linear parabolic equations defined on the whole space. More precisely, we shall investigate conditions which guarantee that the global solutions decay at infinity uniformly in time and their entire trajectory approaches a single steady state as time goes to infinity. Finally, we obtain a characterization of solutions which blow-up, vanish or converge to a stationary state for initial data of the form $λφ_0$ while $λ>0$ crosses a bifurcation value $λ_0$.
