    CMSA 20 Garden Street Cambridge, Massachusetts 02138 United States

    Math and Machine Learning Reunion Workshop Dates: September 8–10, 2025 Location: Harvard CMSA, Room G10, 20 Garden Street, Cambridge MA Machine learning and AI are increasingly important tools in all fields of research. In the fall of 2024, the CMSA Mathematics and Machine Learning Program hosted 70 mathematicians and machine learning experts, ranging from beginners to […]

  • Higher categories of cobordisms

    Science Center 507 1 Oxford Street, Cambridge

    Geometry and Quantum Theory Seminar Speaker: Lorenzo Riva Title: Higher categories of cobordisms Abstract: I will give a brief introduction to topological field theories from a higher categorical perspective. After saying a few things about higher categories, I will define a family of n-categories of bordisms and talk about their universal properties. I will try […]

  • The Geometry of Machine Learning

    CMSA 20 Garden Street Cambridge, Massachusetts 02138 United States

    The Geometry of Machine Learning Dates: September 15–18, 2025 Location: Harvard CMSA, Room G10, 20 Garden Street, Cambridge MA 02138 Despite the extraordinary progress in large language models, mathematicians suspect that other dimensions of intelligence must be defined and simulated to complete the picture. Geometric and symbolic reasoning are among these. In fact, there seems […]

  • Orientifolds for F-theory on K3 Surfaces

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

    Quantum Field Theory and Physical Mathematics Seminar Speaker: Chuck Doran (Alberta/CMSA) Title: Orientifolds for F-theory on K3 Surfaces Abstract: Compactification of F-theory on an elliptically fibered K3 surface provides a framework to encode type IIB string theory on elliptic curves, with the Kaehler modulus of the elliptic curve encoded in the complex structure of the elliptic fibers. In […]

  • Topological Manifolds – The First 100 Years

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

    Colloquium Speaker: Michael Freedman (Harvard CMSA and Logical Intelligence) Title: Topological Manifolds – The First 100 Years Abstract: I’ll review manifold topology in the topological category from its start with work of Rado (1925) and Kneser (1926) to the present. Work of Moise, Mazur, Kirby, Siebenmann, Sullivan, Kruskal, and the speaker will be discussed. In my view […]

The Seven Millenium Problems provide an […]

  • Moduli spaces of 4d N=2 quantum field theories

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

    Differential Geometry and Physics Seminar Speaker: Robert Moscrop, CMSA Title: Moduli spaces of 4d N=2 quantum field theories Abstract: Supersymmetry endows quantum field theories with several rich algebraic and geometric structures associated to their moduli space of vacua, providing powerful tools to study such theories non-perturbatively. For example, in four-dimensional theories with eight supercharges, the […]

  • Top-Down Perspectives on Symmetry Theories

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

    Member Seminar Speaker: Max Hubner Title: Top-Down Perspectives on Symmetry Theories Abstract: I will review the construction and utility of symmetry theories for string constructed quantum field theories. Symmetry theories are extra-dimensional auxiliary theories separating aspects of a quantum field theory's symmetries from many of its more messy features. For QFTs with extra-dimensional string constructions the […]

  • Non-Supersymmetric Orbifolds, Quivers and Chen-Ruan Orbifold Cohomology

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

    Quantum Field Theory and Physical Mathematics Seminar Speaker: Max Hübner (Uppsala & CMSA) Title: Non-Supersymmetric Orbifolds, Quivers and Chen-Ruan Orbifold Cohomology Abstract: We consider D3-brane probes of non-supersymmetric orbifolds and IIA on the same class of non-supersymmetric orbifolds. Both setups are characterized, in part, by quivers (which in the latter case relate for example to D0-brane probes) from which […]
