Dissipative quasi-geostrophic equations with \(L^p\) data
Electronic journal of differential equations, Tome 2001 (2001)
We seek solutions of the initial value problem for the 2D dissipative quasi-geostrophic (QG) equation with $L^{p}$ initial data. The 2D dissipative QG equation is a two dimensional model of the 3D incompressible Navier-Stokes equations. We prove global existence and uniqueness of regular solutions for the dissipative QG equation with sub-critical powers. For the QG equation with critical or super-critical powers, we establish explicit global $L^{p}$ bounds for its solutions and conclude that any possible finite time singularity must occur in the first order derivative.
