What is Harmonic analysis on the fourfold cover of the space of ordered triangles I: the invariant differentials about?

Denote by $SL_n(\mathbb R)$ the group of $n\times n$ real matrices with determinant one, $A$ the subgroup consisting of the diagonal matrices with positive entries, and $SL_n(\mathbb R)/A$ the manifold of left cosets $gA$, $g\in SL_n(\mathbb R)$. In this paper, we will be concerned with the harmonic analysis on the homogeneous space $SL_n(\mathbb R)/A$ when $n=3$. In particular, we provide explicit generators and their relations for the algebra of the invariant differential operators. Then we prove that some of the non-central generators are essentially self-adjoint.
