de Sitter时空中的半线性Klein-Gordon方程

The semilinear Klein-Gordon equation in de Sitter spacetime

Karen Yagdjian

摘要:

本文研究了具有小质量$m \le n/2$的半线性Klein-Gordon方程$\Box_g ϕ-m^2 ϕ= -|ϕ|^p $在具有度规$g$的de Sitter时空中解的爆破现象.我们证明了对于每个$p>1$,大能量解爆破,而对于小能量解,我们给出了一个边界$p=p(m,n)$的整体时间存在性。考虑的基础上的柯西问题的解决方案的代表性公式和一些推广的加藤引理。

英文摘要:

In this article we study the blow-up phenomena for the solutions of the semilinear Klein-Gordon equation $\Box_g ϕ-m^2 ϕ= -|ϕ|^p $ with the small mass $m \le n/2$ in de Sitter space-time with the metric $g$. We prove that for every $p>1$ the large energy solution blows up, while for the small energy solutions we give a borderline $p=p(m,n)$ for the global in time existence. The consideration is based on the representation formulas for the solution of the Cauchy problem and on some generalizations of the Kato's lemma.
