Existence and uniqueness of the global admissible solution for a viscoelastic model with relaxation
Published online by Cambridge University Press: 14 November 2011
Abstract
This paper examines the Cauchy problem for a viscoelastic model with relaxation
with discontinuous, large initial data, where ½ ≦ μ <1, δ > 0 are constants. We first give a definition of admissible (or entropic) solutions to the system. Under this definition, we prove the existence, uniqueness and continuous dependence of the global admissible solution for the system. Our methods are essentially due to Kruzkov, and the requirement that f(u) is not badly degenerate (more precisely, meas {x: f″(x) = 0} = 0), needed previously when considering the global existence problem for the same system, is removed.
