SUMMARY:Workshop / Seminar:Algebraic Geometry Seminar: Positive cycles on Hilbert schemes of points
DESCRIPTION:Algebraic geometers are often interested in certain “positive” cones that one can associate to varieties\, such as the nef and effective cones. While traditionally studied in the divisor and curves cases\, cones of cycles of intermediate dimension have recently been the subject of much study. We discuss some results on nef and effective cones of intermediate dimension cycles in the case of Hilbert schemes of points. In particular\, we look at the Hilbert scheme of 3 points in $\mathbb{P}^3$. Our computation generalizes results of Ryan & Stathis and requires a careful analysis of the PGL orbits in the Hilbert scheme\, as well as a new basis of the Chow ring inspired by Mallavibarrena and Sols.

SUMMARY:Lecture / Discussion:Democracy Against Workers?
DESCRIPTION:Webinar Link: https://myumi.ch/ww7q9\n\nCanonical models of democracy expect working-class people to be the main beneficiaries -- even the natural beneficiaries -- of democratization. Yet not all democratic systems deliver economic gains to average citizens. Even after they gain the right to vote\, very rarely do they become candidates for office and get to serve as the people's representatives. When is \"democracy against workers\" and how might we make it work better for working people? In this Democracy Week roundtable\, Nick Carnes\, Adam Dean\, and Noam Lupu discuss their book projects on these themes\, with Ann Heffernan serving as respondent.\n\nIf there is anything we can do to make this event accessible to you\, please contact us at emergingdemocracies@umich.edu. Please be aware that advance notice is necessary as some accommodations may require more time for the university to arrange.

SUMMARY:Workshop / Seminar:Optimal Contract\, Delegated Investment\, and Information Acquisition
DESCRIPTION:We study a model of delegated investment within a noisy rational expectations equilibrium framework. Portfolio managers can acquire costly private information about asset payoffs but incur portfolio management costs\, and are compensated by investors to make investment decisions on their behalf. We show that the optimal contract features a benchmark component that mitigates the agency frictions arising from portfolio management costs. The precision of managers' private information is determined endogenously in market equilibrium\, with private and public information acting as substitutes. As portfolio management costs increase\, both the performance-based and benchmark components of the optimal contract become more sensitive to investment outcomes\, while fewer private signals are incorporated into prices\, reducing market informational efficiency. We further show that when a social planner places sufficient weight on the welfare of direct investors and liquidity providers\, the socially optimal equilibrium achieves greater price informational efficiency than the decentralized equilibrium. The talk will focus on the interaction between optimal contracting\, information acquisition\, and market efficiency\, together with the economic intuition underlying these results.

SUMMARY:Workshop / Seminar:Probability and Analysis Seminar: Non-abelian Hirota–Miwa Equations for the KPZ Universality Class
DESCRIPTION:Abstract: The KPZ universality class is a broad collection of mathematical and physical models linked through their shared universal scaling behavior. A privileged subset\, known as exactly solvable models\, possess algebraic structure that allows for exact formulas for their probability distributions.\n\nFor an even smaller subset of these models\, their distributions have been shown to satisfy nonlinear equations from classical integrable systems\, including Painlevé\, KP\, and Toda equations. Why should equations from soliton theory appear in random growth\, and why do they keep reappearing across different models?\n\nI will describe a framework that gives a common algebraic explanation and extends this connection to eighteen exactly solvable models. The framework organizes the Fredholm determinant formulas of solvable KPZ models into an overdetermined linear problem whose compatibility conditions reveal a discrete integrable structure gauge equivalent to the non-abelian Hirota–Miwa equation.
