Global existence and uniqueness of strong solutions to the 2D nonhomogeneous primitive equations with density-dependent viscosity
arxiv(2024)
摘要
This paper is concerned with an initial-boundary value problem of the
two-dimensional inhomogeneous primitive equations with density-dependent
viscosity. The global well-posedness of strong solutions is established,
provided the initial horizontal velocity is suitably small, that is, ∇
u_0_L^2≤η_0 for suitably small η_0>0. The initial data
may contain vacuum. The proof is based on the local well-posedness and the
blow-up criterion proved in , which states that if T^* is the
maximal existence time of the local strong solutions (ρ,u,w,P) and
T^*<∞, then
