Behavior of solutions of 2D quasi-geostrophic equations
- P. Constantin, J. Wu
- Mathematics
- 1 June 1999
We study solutions to the 2D quasi-geostrophic (QGS) equation $$ \frac{\partial \theta}{\partial t}+u\cdot\nabla\theta + \kappa (-\Delta)^{\alpha}\theta=f $$ and prove global existence and uniqueness… Expand

Because of active exchange between surface and groundwater of a karstic hydrological system, the groundwater of Guiyang, the capital city of Guizhou Province, southwest China, has been seriously… Expand
Global Regularity for a Class of Generalized Magnetohydrodynamic Equations
- J. Wu
- Mathematics
- 1 June 2011
It remains unknown whether or not smooth solutions of the 3D incompressible MHD equations can develop finite-time singularities. One major difficulty is due to the fact that the dissipation given by… Expand
Two regularity criteria for the 3D MHD equations
This work establishes two regularity criteria for the 3D incompressible MHD equations. The first one is in terms of the derivative of the velocity field in one direction while the second one requires… Expand

- Mathematics
- 21 January 2007
Abstract We present a regularity result for weak solutions of the 2D quasi-geostrophic equation with supercritical ( α 1 / 2 ) dissipation ( − Δ ) α : If a Leray–Hopf weak solution is Holder… Expand
Regularity Criteria for the Generalized MHD Equations

Lower Bounds for an Integral Involving Fractional Laplacians and the Generalized Navier-Stokes Equations in Besov Spaces
- J. Wu
- Mathematics
- 1 May 2006
When estimating solutions of dissipative partial differential equations in Lp-related spaces, we often need lower bounds for an integral involving the dissipative term. If the dissipative term is… Expand
