1Global Smooth Solutions to the 2-D Inhomogeneous Navier-Stokes Equations with Variable Viscosity显示文摘Under the assumptions that the initial density ρ0 is close enough to 1 and ρ0-1∈Hs+1(R2);u0∈Hs(R2)∩H_∈(R2) for s>2 and 0<ε<1;the authors prove the global existence and uniqueness of smooth solutions to the 2-D inhomogeneous Navier-Stokes equations with the viscous coefficient depending on the density of the fluid.Furthermore,the L2 decay rate of the velocity field is obtained.Guilong GUI Ping ZHANG 2009Chinese Annals of Mathematics,Series B2009,30,5:2
2Lagrangian Approach to Global Well-Posedness of the Viscous Surface Wave Equations Without Surface Tension显示文摘In this paper,we revisit the global well-posedness of the classical viscous surface waves in the absence of surface tension effect with the reference domain being the horizontal infinite slab,for which the first complete proof was given in Guo-Tice[Anal.PDE 6,1429-1533(2013)]via a hybrid of Eulerian and Lagrangian schemes.The fluid dynamics are governed by the gravity-driven incompressible Navier-Stokes equations.Even though Lagrangian formulation is most natural to study free boundary value problems for incompressible flows,few mathematical works for global existence are based on such an approach in the absence of surface ten-sion effect,due to breakdown of Beale’s transformation.We develop a mathematical approach to establish global well-posedness based on the Lagrangian framework by analyzing suitable“good unknowns”associated with the problem,which requires no nonlinear compatibility conditions on the initial data.Guilong Gui 2021Peking Mathematical Journal2021,4,1:2
