On the analyticity and gevrey regularity of solutions to the three-dimensional inviscid Boussinesq equations in a half space

In this paper, we address the problem of analyticity up to the boundary to the 3D inviscid Boussinesq equations in a half space $\mathbb{R}^3_+$. Furthermore, we prove the persistence of Gevrey regularity and obtain lower bounds on the radius of Gevrey regularity.
