摘要: 讨论初值问题 整体经典解的存在性。该问题来源于粘弹性力学。在关于已知函数的一些正则性假设和p'(s)≥c1>0,|q'(s)|≤const,λ(0)<0,λ'(0)<λ2(0)的条件下,通过能量估计,证明了该问题整体经典解的存在性。Abstract: In this paper,the problem of global existence of solutions to the followin g initial value problem is studied: which comes from viscoelastic mechanics.By making u se of integral estimates method,it is proved that this problem has a global solution if,in addition to certain regularity assumptions on the given fun ctions,the following conditions are satisfied: p'(s)≥c1>0,|q'(s)|≤const,λ(0)<0,λ'(0)<λ2(0).
