Abstract
We study the global well-posedness of the initial-value problem for the 2D Boussinesq-Navier-Stokes equations with dissipation given by an operator L that can be defined through both an integral kernel and a Fourier multiplier.When the opera-tor L is represented by|ζ|/a(|ζ|) with a satisfying lim|ζ|→∞a(|ζ|)/|ζ|σ=0 for any σ>0,we obtain the global well-posedness.A special consequence is the global well-posedness of 2D Boussinesq-Navier-Stokes equations when the dissipation is logarithmically supercrit-ical.
