This paper studies quantum invariant differential operators for quantum symmetric spaces in the maximally split case. The main results are quantum versions of t

In this paper the authors apply their results on the geometry of polygons in infinitesimal symmetric spaces and symmetric spaces and buildings to four problems

The authors prove a general form of the sum formula $\mathrm{SL}_2$ over a totally real number field. This formula relates sums of Kloosterman sums to products
