摘  要: This talk is concerned with the problem of energy conservation for the two-dimensional inhomogeneous Euler equations. In particular, two types of sufficient conditions are obtained. The first one assumes Lp-regularity on the spatial gradient of the density and the vorticity. The second one removes the regularity condition on the spatial gradient of the density while requires certain time regularity of the vorticity. Furthermore, we phrase the energy

spectrum in terms of the Littlewood-Paley decomposition and show that the energy flux vanishes as the dyadic exponent goes to infinity.
