The tropical connection is used to produce Lorentzian polynomials from discrete convex functions, leading for example to a short proof of Mason's conjecture on the number of independent sets of a matroid. This lecture series will explore the intricate relationships among Grassmannians over hyperfields, dequantization processes, and the theory of Lorentzian polynomials. In ongoing collaborative work with Matt Baker, Mario Kummer, and Oliver Lorscheid, we extend the connection between Lorentzian polynomials and discrete convex functions to matroids over triangular hyperfields, as introduced by Viro. This extension deepens our understanding of the space of Lorentzian polynomials, revealing a complex interplay among analysis, combinatorics, and geometry.\r\n\r\nThe three lectures in this series are designed to be accessible to a broad audience and appropriate for a Department Colloquium.\r\n\r\nAmong his many honors, Prof. Huh is a recipient of the Fields Medal (2022), the MacArthur Fellowship (2022), and the New Horizons in Mathematics Prize (2019).

Participants will develop a deeper understanding of what the term \u201ccommunity engagement\u201d means, as well as the many forms it might take - from research and course-based projects to philanthropy, activism, policy, and direct service. Across all these forms of engagement, participants will learn concepts and actions that promote equitable partnerships, center community-defined priorities, and disrupt entrenched power dynamics between universities and community members. Participants will also discuss real-world community engagement scenarios that ask them to apply what they\u2019ve learned in the workshop to various situations.\r\n\r\n**This workshop is an updated version of Ginsberg\u2019s long-standing Entering, Engaging, and Exiting (E3) session.
