SUMMARY:Workshop / Seminar:Commutative Algebra Seminar: Subadditivity of Shifts for Monomial Ideals and Shuffle products in Lattices
DESCRIPTION:We prove that the maximal shifts in the minimal free resolution of a monomial ideal form a subadditive sequence\, settling a conjecture of Avramov\, Conca and Iyengar. To do so\, we develop explicit chain-level models for the homology of posets and lattices\, introduce an Eilenberg–Zilber–type shuffle product in the lattice setting\, and use it to derive nonvanishing criteria for lattice homology classes that yield the desired subadditivity of maximal shifts. The talk is based on joint work with K. Adiprasito\, A. Björner\, M. Margaritis\, and V. Welker (arXiv:2404.16643).\n\nThis is a hybrid talk.

SUMMARY:Workshop / Seminar:RCGD Seminar Series on Social Connection: Anastaskia Makhanova
DESCRIPTION:Anastasia Makhanova\nUniversity of Arkansas\nJan. 26\, 2026\n\nABOUT THE SERIES\n\nThe Winter 2026 RCGD Seminar Series: The Ties that Bond: Interdisciplinary Perspectives on Social Connection\n\nThis seminar series brings together senior and early-career scholars to explore fundamental questions about how we connect\, protect\, and care. Talks will highlight lifespan and comparative approaches to understanding social connection\, physiological implications of social and race-related stressors\, and diverse conceptualizations of what it means to belong—from romantic and parent–child relationships to group and societal dynamics to technology-mediated interactions.\n\nRobin Edelstein\, Professor of Psychology at the University of Michigan and an affiliate of the Research Center for Group Dynamics\, has organized this series. She will introduce the series at this kick-off event that doubles as a faculty meeting.\n\nThe first seminar in the series will be Jan. 26. Join us on Mondays to learn about the biological\, social\, and developmental pathways that shape human connection.\n\nThese events are held Mondays from 3:30 to 5.\nIn person: ISR Thompson 1430\, unless otherwise specified.\nOrganized by Robin Edelstein\nAs permissions allow\, seminars are later posted to our YouTube playlist.
