#### Symmetric group representations and Z

Abstract: We discuss implications of the following statement about the representation theory of symmetric groups: every integer appears infinitely often as an irreducible character evaluation, and every nonnegative integer appears infinitely often as a Littlewood-Richardson coefficient and as a Kronecker coefficient. This is joint work with A. Yong.

#### Higgs bundle and related "physics"

###### Lutian Zhao (Illinois Math)

Abstract: Higgs bundle was a math term introduced by Nigel Hitchin as a rough analogue of Higgs boson in standard model of physics. It turns out that it is deeply rooted in the N=4 super Yang-Mills world, where Kapustin and Witten realize the geometric Langlands correspondence as a special case of S-duality. In this talk. I'll introduce the history and notion of the Higgs bundle, and try to talk about some of the idea in their "proof". No knowledge of physics is assumed.

#### Rehumanizing Mathematics: A Vision for the Future

###### Dr. Rochelle Gutierrez   [email] (Illinois, Department of Curriculum and Instruction)

Abstract: In this session, Dr. Gutiérrez will reorient the audience away from a long established "equity" standpoint towards reframing the goal as rehumanizing mathematics. In particular, she will highlight 1) what may constitute dehumanizing practices/experiences in mathematics classrooms and 2) what can be done so that students and teachers are provided with both windows and mirrors onto the world and ways of relating to each other with dignity through mathematics. Specific examples of what one might look for in a rehumanized mathematics classroom will be provided.
