Well-posedness for density-dependent Boussinesq equations without dissipation terms in Besov spaces

In this paper, we consider the N-dimensional incompressible density-dependent Boussinesq equations without dissipation terms (N≥2). We establish the local well-posedness for the incompressible Boussinesq system under the framework of the Besov spaces. In addition, we also obtain a Beale-Kato-Majda-type regularity criterion.
