Existence of a Global Solution for a Viscoelastic System
Copyright policy )Existence of a Global Solution for a Viscoelastic System
The author considers the Cauchy problem for the viscoelastic system \[ v_t- u_x= 0,\quad u_t- f(v)_x+ ku= u_{xx} \] without the restriction that the initial data approach constants at infinity. Existence of unique classical solution is proved, including a priori estimates. A parallel result for a model of compressible adiabatic flow through porous media with a physical viscosity is also obtained.
