Well-posedness results for a sixth-order logarithmic Boussinesq equation

Abstract: The main goal of this paper is to study for a sixth-order logarithmic Boussinesq equation. We obtain several results: Firstly, by using Feado-Galerkin method and a logaritmic Sobolev inequality, we proved global existence of solutions. Later, we proved blow up property in infinity time of solutions. Finally, we showed the decay estimates result of the solutions. for two-way propagation of shallow water waves. For contributions related to (2), we refer to [4, 5, 10-14]. Wazwaz [15] studied the logarithmic Bouss… Show more

“…Cause of this is interest in it occures naturally in inflation cosmology, nuclear physics, supersymmetric field theories and quantum mechanics (see [3,5,10]). Later, by the motivation of this work, some authors gave necessary and sufficient conditions for the hyperbolic equation with logarithmic source term (see [6,12,15,16]).…”

“…Also, He et al [5] proved the decay and the finite time blow-up for weak solutions of the equation, by using the potential well technique and concave technique. Recently many other authors investigated higher-order hyperbolic and parabolic type equation [2,3,6,[11][12][13][14][15]. Ishige et al [6] studied the Cauchy problem for nonlinear higher-order heat equation as follows…”
