摘要 主要研究一类具有记忆项的二阶非线性发展方程的能量衰减估计,通过运用积分不等式以及索布列夫空间嵌入定理,证明该方程柔和解的能量呈指数衰减。 The paper studied the energy decay estimates for general second order nonlinear evolution equations with memory. Based on the integral inequality and Sobolev embedding theorem,it has been confirmed that the energy of mild solution decays with exponential rate.
