摘要：
In this paper, we investigate the Cauchy problem for the two-dimensional (2D) incompressible Bollard equations. On the one hand, we prove global-in-time existence of smooth solutions to the 2D Benard equations with critical dissipation. On the other hand, we establish several regularity criteria involving temperature for 2D Benard equations with supercritical dissipation. (C) 2017 Elsevier Ltd. All rights reserved.
