摘要
In this paper, we consider the blow-up criterion for the quasi-geostrophic equations with dissipation Lambda(gamma) (0 < gamma < 1). By establishing a new trilinear estimate, we show that if theta is an element of L gamma/gamma+s-1(0, T; B-infinity,infinity(s) (R-2) ) for some s is an element of (1 - gamma/2, 1), then the solution can be extended smoothly past T. This improves and extends the corresponding results in Dong and Pavlovic (2009) ([32]) and Yuan (2010). (C) 2017 Elsevier Ltd. All rights reserved.
