Zhang, Ping et Zheng , Yuxi, On the existence and uniqueness of solutions to an asymptotic equation of a variational wave equation, Acta mathematica Sinica. English series (Print) , 15(1), 1999, pp. 115-129
We prove the global existence and uniqueness of admissible weak solutions to an asymptotic equation of a nonlinear hyperbolic variational wave equation with nonnegative L 2(.) initial data.
