de Sitter时空中Wave Equations解的寿命

Lifespan of Solutions to Wave Equations on de Sitter Spacetime

Weiping Yan

摘要:

本文考虑deSitter时空\begin{eqnarray*} &&\square_g=F(u),\\ &&\square_g=F(\partial_tu,\nabla u). \end{eqnarray*}上的两类非线性波动方程解的有限时间爆破。这个证明是基于一个新的爆破准则,它推广了Sideris \cite{Sider}中的爆破准则。此外,我们给出了该问题解的寿命估计。

英文摘要:

In this paper, we consider the finite time blow up of solutions for the following two kinds of nonlinear wave equations on de Sitter spacetime \begin{eqnarray*} &&\square_g=F(u),\\ &&\square_g=F(\partial_tu,\nabla u). \end{eqnarray*} This proof is based on a new blow up criterion, which generalize the blow up criterion in Sideris \cite{Sider}. Furthermore, we give the lifespan estimate of solutions for the problems.
