Matsuki duality for loop groups

Tsao-Hsien Chen, Lingfei Yi

We establish versions of Matsuki duality for loop groups. The main result is a bijection between symmetric loop group orbits and real polynomial loop group orbits on the affine Gra…

Frobenius structure on rigid connections and arithmetic applications

Daxin Xu, Lingfei Yi

We construct the natural Frobenius structures on two families of rigid irregular $G ˇ$ -connections on $G_{m}$ (or $A^{1}$ ) for a split simple group $G ˇ$ :…
