讨论拟线性双曲方程ut+(u^m)x=t^qu^p,以σ-有限的Borel测度为初值的Cauchy问题,其中m〉1,0〈P≤1,q≥0是给定常数,证明了BV解的存在性.
The aim of the present paper is to discuss the Cauchy problem for a class of quasilinear hyper- bolic equations of the form ut+(u^m)x=t^qu^p with σ- finite Borel measures as initial conditions, where m〉1,0〈P≤1,q≥0 are some given real numbers,the existence of BV solutions for the above problem is obtained.
