SUMMARY:Conference / Symposium:Scott Pranger ALS Center Symposium
DESCRIPTION:The first of an annual symposium that will celebrate the naming of the Scott Pranger ALS Center at Michigan Medicine on September 25\, 2026\, at 2:30 p.m.\, in the Kahn Auditorium of the A. Alfred Taubman Biomedical Science Research Building.\n\nJoin leading faculty\, researchers\, advocates\, and members of the ALS community for an inspiring day dedicated to amyotrophic lateral sclerosis (ALS) and improving the lives of those affected by the disease.\n\nThe event will feature a recorded discussion with Sanjay Gupta\, M.D.\, the award-winning chief medical correspondent for CNN\, talking about his new book on pain\, an often overlooked burden for those living with ALS.\n\nFollowing his keynote will be a live panel discussion led by Center Director Eva L. Feldman\, M.D.\, Ph.D.\, on pain.  She will be joined by leading pain experts—Chad Brummett\, M.D.\, Daniel J. Clauw\, M.D.\, and Jill Schneiderhan\, M.D.—and Stanford Morris ALS Clinic Director Stephen Goutman\, M.D.\, M.S.\n\nThe afternoon will also feature special messages from U.S. Representative Debbie Dingell\, former U-M Men’s Basketball Coach Steve Fisher (recorded)\, and Michigan Medicine interim CEO Ganesh S. Palapattu\, M.D.\, along with members of the ALS community\, including Scott Pranger\, James A. Hiller\, Esq.\, and Dr. Feldman.  There will also be a special discussion between Dr. Goutman and Ken Mercer\, who is living with ALS.\n\nThe event is open to the public.  Following the symposium\, a reception open to all will be held in the Gilbert S. Omenn Atrium at 4:15 p.m.

SUMMARY:Workshop / Seminar:A tale of two polynomials: positivity in wonderful varieties and matroids
DESCRIPTION:I will share a story of two polynomials\, the Poincarè polynomial of Chow rings of toric varieties of matroids\, and the h-polynomials of nested set complexes of matroids. The story is set in a rich network of positivity properties coming from geometry and combinatorics of matroids\, with connections to moduli spaces of rational stable curves. The main theorems are matroidal analogues of Gal’s conjecture\, and real-rootedness of some of these polynomials. (Joint works with Basile Coron\, and Luis Ferroni)

SUMMARY:Lecture / Discussion:AIM Seminar:  Discrete structure\, continuous dynamics: graph-theoretic approaches and singular parametric limits in biochemical reaction networks
DESCRIPTION:Abstract: A biochemical reaction network is based on a discrete object: a directed graph whose edges are labeled with reaction rates. At the same time\, it is governed by continuous dynamics\, typically expressed as a nonlinear system of polynomial ODEs. These two descriptions encode the same system but have fundamentally different mathematical structures. This mathematical tension raises the question: how does the discrete structure of a biochemical network govern its continuous dynamics? In this talk\, I will explore this question through several examples at the intersection of graph theory\, dynamical systems\, and applied algebraic geometry. In particular\, I will focus on singular limits in which reaction-rate parameters tend to infinity. These limits motivate a graph operation that resembles an edge contraction\, and I will examine their effects on graph invariants expressed as rational functions of the model parameters. I will then extend this construction to structural identifiability and discuss how model reduction alters the geometry of parameter space. Finally\, I will turn to a stochastic interpretation of this graph-theoretic framework and describe how asymmetry in the spectral decomposition of a finite-state continuous-time Markov process gives rise to a signature of departure from thermodynamic equilibrium\, with unexpectedly nonmonotone behavior even on the simplest networks. I will conclude with a discussion of broader future directions focused on understanding how network operations may affect qualitative dynamical properties of the system. Together\, these examples illustrate how biologically inspired networks generate subtle structural questions and new mathematics at the interface of discrete and continuous systems.\n\nContact:  Zhiyan Ding

SUMMARY:Workshop / Seminar:Derived categories in algebraic geometry
DESCRIPTION:Derived categories have found interest in algebraic geometry for two reasons: 1) as a tool for cohomological calculations and derived functors\, and 2) as an interesting invariant in its own right. I will briefly survey both perspectives.

SUMMARY:Lecture / Discussion:HET Seminar | Birefringence and Axiogenesis
DESCRIPTION:Recent analyses of Planck and ACT CMB data report a 2–4σ hint of isotropic cosmic birefringence of β ≈ 0.3°. This corresponds to a parity-violating rotation of CMB photon polarization and points to new physics beyond the Standard Model. We demonstrate that cosmic birefringence and the baryon asymmetry can be simultaneously explained by the rotation of an axion in field space. In this axiogenesis framework\, the axion rotation generates the baryon asymmetry through electroweak sphalerons\, while such a rotation can arise in the early universe from explicit U(1) symmetry breaking expected from quantum gravity. The minimal models predict the correct sign of β based on the observed baryon asymmetry\, as well as a period of matter and kination domination ending around a temperature of 3-50 MeV that makes the models falsifiable through future astrophysical probes and can lead to unique gravitational-wave signatures.

SUMMARY:Lecture / Discussion:Incorporations: Capitalism and Collective Life with Associate Professor Matthew Hull
DESCRIPTION:Join the U-M Department of Anthropology for the annual Roy A. Rappaport Lecture Series! Associate Professor Matthew Hull will present the fall 2026 series\, titled “Incorporations: Capitalism and Collective Life.”\n\nAbstract: “Corporations are often seen as purely economic actors\, but they have been central to Anglo-American governance for centuries—pioneers of democratic assembly\, speech\, citizenship\, and constitutions. Many features of corporations\, once grounded in democratic ideals\, now foster the unresponsiveness of these institutions. These lectures will include discussion of a diverse array of corporations: medieval guilds\, the English East India Company\, Alaska Native corporations\, and caste-based corporations in India.”\n\nRappaport lectures will take place on the following fall Fridays from 3 to 4:30 p.m. in West Hall Room 411. They are free and open to the public:\n\nFriday\, Sept. 25\n“Corporate Persons in Human Law: Reproduction\, Kinship\, Jurisdiction”\n\nFriday\, Oct. 23\n“Freedom and Citizenship: Corporate Membership and the Making of Exclusion”\n\nFriday\, Nov. 13\n“Meetings and Speech: Corporate Mediations of Will”\n\nFriday\, Dec. 4\n“Sharing and Inequality in Corporations”\n\nVIRTUAL PARTICIPATION LINK: https://umich.zoom.us/j/91475190155\n\nREGISTRATION IS APPRECIATED for planning purposes: https://myumi.ch/e77Ax\n\nIf you need accommodations to attend\, please email anthro.exec.secretary@umich.edu.\n\nABOUT ASSOCIATE PROFESSOR MATTHEW HULL\nMatthew Hull is Associate Professor of Anthropology at the University of Michigan. His research focuses on the nexus of signification\, technology\, and institutions. His book\, “Government of Paper: The Materiality of Bureaucracy in Urban Pakistan\,” winner of the 2019 J.I. Staley Prize from the School of Advanced Research\, examines governance as a semiotic and material practice. He has worked on urban planning in 1960s India and police communication systems and lotteries in contemporary India. He is currently writing a book on how early modern corporations shaped democratic governance and continue to structure contemporary political life.
