半线性阻尼wave equations弱耦合系统非线性临界正则性的相互影响

The interplay of critical regularity of nonlinearities in a weakly coupled system of semi-linear damped wave equations

Tuan Anh Dao, Michael Reissig

摘要:

研究一类半线性经典阻尼波方程组的弱耦合系统,其非线性项具有连续模,其幂属于$p-q$平面上的临界曲线.本文的主要目标是找出这些连续模的尖锐条件,分类之间的整体(在时间上)存在的小数据的解决方案和有限时间爆破的解决方案。

英文摘要:

We would like to study a weakly coupled system of semi-linear classical damped wave equations with moduli of continuity in nonlinearities whose powers belong to the critical curve in the $p-q$ plane. The main goal of this paper is to find out the sharp conditions of these moduli of continuity which classify between global (in time) existence of small data solutions and finite time blow-up of solutions.
