Abstract:

In this paper we study the Cauchy problem for one multidimensional compressible nonlocal model of the dissipative quasi-geostrophic equations and discuss the e ff ect of the sign of initial data on the wellposedness of this model. First, we prove the existence and uniqueness of local smooth solutions for the Cauchy problem for the model with the nonnegative initial data, which seems to imply that whether the well-posedness of this model holds or not depends heavily upon the sign of the initial data even for the subcritical case. Secondly, for the sub-critical case 1 < alpha <= 2, we obtain the global existence and uniqueness results of the nonnegative smooth solution. Next, we prove the global existence of the weak solution for 0 < alpha <= 2 and upsilon > 0. Finally, for the sub-critical case 1 < alpha <= 2, we establish H-beta (beta >= 0) and L-p (p >= 2) decay rates of the smooth solution as t -> infinity. A inequality for the Riesz transformation is also established.
