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…
