一类带阻尼项和记忆项的波动方程解的爆破
The Blow-up of Solutions to a Class of Wave Equations with Damping and Memory Terms
摘要
Abstract
This study investigates the initial-boundary value problem for a weakly damped wave equa-tion with composite memory terms in an n-dimensional exterior domain.A multiplier is adopted to off-set disturbances from weak damping.Via energy functional construction,proper test function selection and recursive iterative sequence formulation,finite-time blow-up of solutions is verified for various spatial dimensions,alongside an upper bound estimate of the solution lifespan.关键词
