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.
