Titles and abstracts:
| Speaker | Affiliation | Title | |||
| Shuichiro Takeda | Osaka University | Distinguished representations and dual groups | |||
| Abstract: I will give an overview of basic theory of distinguished representations of $p$-adic groups especially in the context of symmetric spaces. In particular, I will talk about how to compute the dual groups of symmetric spaces with concrete examples and how they fit into the framework of the theory of relative matrix coefficients. | |||||
| Chen Wan | Rutgers University | An introduction to the relative Langlands program | |||
| Abstract: In these talks, I will give an overview of the relative Langlands program, with an emphasis on period integrals and local multiplicity. I will start with some basic examples, then I will move to the “classical” setting of spherical varieties. Lastly I will discuss the more general setting of the relative Langlands duality. About half of the talks will be about the local aspect and the other half will be about the global setting. I will give as many specific examples as possible. | |||||
