Racke, Reinhard Said-Houari, Belkacem Racke, Reinhard 2019-03-15T08:56:19Z eng Global well-posedness of the Cauchy problem for the Jordan-Moore-Gibson-Thompson equation terms-of-use In this paper, we consider the Cauchy problem of a third order in time nonlinear equation known as the Jordan-Moore-Gibson-Thompson equation arising in acoustics as an alternative model to the well-known Kuznetsov equation. First, using the contraction mapping theorem, we show a local existence result in appropriate function spaces. Second, by using the energy method together with a bootstrap argument, we prove a global existence result for small data. Third, polynomial decay rates in time for the solution will be obtained for space dimensions N >=2. 2019-03-15T08:56:19Z Said-Houari, Belkacem 2019
