  • The Geometry of Machine Learning 2026

    Featured
    CMSA 20 Garden Street Cambridge, Massachusetts 02138 United States

    The Geometry of Machine Learning 2026 Dates: September 8–11, 2026 Location: Harvard CMSA, Room G10, 20 Garden Street, Cambridge MA 02138 & via Zoom Webinar Large language models are presently, and will increasingly, be complemented by other dimensions of intelligence: formal verification and energy-based optimizers, becoming parts of larger ecosystems. Can AIs reason geometrically and […]

  • Quasi-local algebras and invertible phases of matter

    Science Center 507 1 Oxford Street, Cambridge

    Geometry and Quantum Theory Seminar Speaker: Nikita Sopenko, CMSA Title: Quasi-local algebras and invertible phases of matter Abstract: In the algebraic approach to quantum field theory, observables localized in bounded regions form a net of von Neumann algebras generating what is known as a quasi-local algebra. I will discuss the classification of quasi-local algebras under […]

  • Working with LLMs to do high quality math

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    https://youtu.be/0wL8NlhxXcU AI for the Working Mathematician Speaker: Daniel Litt, University of Toronto Title: Working with LLMs to do high quality math Abstract: Much hay has been made of the capabilities of LLMs to do math autonomously, and indeed frontier models have resolved some long-standing, interesting open questions. But our goal is not to produce papers, but […]

  • Higher Virasoro algebras

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Geometry and Mathematical Physics Seminar Speaker: Brian Williams, Boston University Title: Higher Virasoro algebras Abstract: I will introduce and classify central extensions of the dg Lie algebra of derived global sections of the tangent sheaf on the punctured d-disk for d > 1. Then, I will formulate and sketch the proof of a formal and […]

  • A beginner’s guide to quantum unique ergodicity

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Member Seminar Speaker: Elena Kim Title: A beginner's guide to quantum unique ergodicity Abstract: The Quantum Unique Ergodicity conjecture is one of the main open questions in quantum chaos. I will explain the conjecture and the progress towards its resolution.
