SUMMARY:Livestream / Virtual:Democracy Needs You
DESCRIPTION:Join us for a live panel discussion exploring how democracy works in practice and what it means for everyday civic life. Faculty experts will expand on key concepts from the Democracy and Civic Engagement Teach-Out®\, including how governments and elections work\, how people and communities influence public decisions\, the role of information and media\, and the challenges that can weaken democratic systems. The conversation will center on clear\, accessible questions and invite learners to consider how informed participation\, strong institutions\, accountability\, and civic action contribute to a healthy democracy. Learners will also have an opportunity to engage with the panel through a moderated Q&A.

SUMMARY:Workshop / Seminar:Learning Seminar in Algebraic Combinatorics
DESCRIPTION:This talk will be an introduction to Nakajima quiver varieties\, focusing on type A quivers. We will begin with a brief recount of quiver representations\, including discussion of kernels and indecomposables. We will define the notion of framing\, and impose a ``stability condition\" on framed quiver representations to obtain what we will call pre-quiver varieties\, of which the Grassmannians and complete flag varieties are examples. Next\, we will introduce the doubled framed quiver. Imposing both the stability condition and additional \"moment map condition\" on doubled framed quiver representations yields the notion of a Nakajima quiver variety. Examples include cotangent bundles of Grassmannians and complete flag varieties.

SUMMARY:Workshop / Seminar:Student Number Theory: An Introduction to Perfectoid Theory
DESCRIPTION:Nearly fifteen years ago\, Peter Scholze introduced perfectoid fields\, establishing a bridge between deeply ramified fields of characteristic zero and characteristic (p). Perfectoid theory has since found important applications in arithmetic geometry. In this talk\, I will follow Scholze’s original paper to give an introduction to perfectoid fields and\, if time permits\, perfectoid spaces.

SUMMARY:Workshop / Seminar:Entropy-Regularized Finite-State Mean Field Control Problems
DESCRIPTION:We study an infinite-horizon discounted mean field control problem for finite-state nonlinear continuous-time Markov chains. Controls are locally integrable transition-rate matrices and are penalized by relative entropy with respect to a state-dependent reference generator. We prove that the value function is the unique bounded viscosity solution on the closed simplex of the Hamilton–Jacobi–Bellman equation by a direct dynamic-programming argument and a finite-state comparison principle. Under a uniform semiconvexity condition and C¹\,¹ regularity\, the value function is globally semiconvex and intrinsically C¹\,¹ on the closed simplex and yields a Gibbs feedback that is the unique Hamiltonian minimizer at interior states. For positive\, symmetric\, possibly state-dependent reference rates\, an entropy-plus-value free energy decays globally exponentially when the temperature parameter is compatible with the semiconvexity modulus. We also establish a discounted planner-to-game correspondence for potential mean field games under a state-independent reference generator.
