带组合非线性项的双波动方程耦合系统解的破裂
Blow-up of solutions to a coupled system of double wave equations with combined nonlinearities
摘要
Abstract
This paper aims to investigate blow-up dynamics of solutions to the small data Cauchy problem for a coupled system of double wave equations with combined nonlinearities.By establishing lower bound estimates of the constructed functionals and using iteration method,blow-up and upper bound lifespan estimate of solutions in the sub-critical case was deduced.关键词
