Singularities of orbit closures in loop spaces of symmetric varieties II: twisted cases
Tsao-Hsien Chen, Lingfei Yi
We study the singularities of orbit closures in loop symmetric varieties, extending our previous work https://arxiv.org/abs/2310.20006 to the twisted setting. We prove that the IC…
Loop spaces, twistor and tempiric parameters
Tsao-Hsien Chen, Lingfei Yi
We establish bijections among spherical orbits on loop symmetric spaces, principal bundles on the twistor , and tempiric Langlands parameters. Using Vogan's theory of…
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 -connections on (or ) for a split simple group :…
