During the 2026–27 academic year, the CMSA will be hosting a Colloquium series, organized by Tobias Schmidt, Houcine Ben Dali, Francesco Mori, and Michal Shavit.

It will take place on Mondays from 4:30 – 5:30 pm (Eastern Time) in Room G10, CMSA, 20 Garden Street. All CMSA postdocs/members are required to attend the weekly CMSA Colloquium series as well as the weekly CMSA Members’ Seminars.

The schedule will be updated as talks are confirmed.

  • The Cubical Route to Understanding Groups

    Speaker: Daniel Wise (McGill University) Title: The Cubical Route to Understanding Groups Abstract: Cube complexes have come to play an increasingly central role within geometric group theory, as their connection to right-angled Artin groups provides a powerful […]

  • Quantum Money from Lattices

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker: Peter Shor (MIT) Title: Quantum Money from Lattices Abstract: Quantum money is a cryptographic protocol for quantum computers. A quantum money protocol consists of a quantum state which can be created (by the mint) and verified (by anybody with a quantum computer who knows what the "serial […]

  • Derandomizing Algorithms via Spectral Graph Theory

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker: Salil Vadhan (Harvard) Title: Derandomizing Algorithms via Spectral Graph Theory Abstract: Randomization is a powerful tool for algorithms; it is often easier to design efficient algorithms if we allow the algorithms to "toss coins" […]

  • Stability of spacetimes with supersymmetric compactifications

    Virtual

    Speaker: Lars Andersson (Max-Planck Institute for Gravitational Physics) Title: Stability of spacetimes with supersymmetric compactifications Abstract: Spacetimes with compact directions, which have special holonomy such as Calabi-Yau spaces, play an important role in supergravity and […]

  • Re-pricing avalanches

    Virtual

    Speaker: Jose A. Scheinkman (Columbia) Title: Re-pricing avalanches Abstract: Monthly aggregate price changes exhibit chronic fluctuations but the aggregate shocks that drive these fluctuations are often elusive.  Macroeconomic models often add stochastic macro-level shocks such as […]

  • Hyperbolic Geometry and Quantum Invariants

    Virtual

    Speaker: Tian Yang (Texas A&M University) Title: Hyperbolic Geometry and Quantum Invariants Abstract: There are two very different approaches to 3-dimensional topology, the hyperbolic geometry following the work of Thurston and the quantum invariants […]

  • CMSA Colloquium 9/15/2021 – 5/25/2022

    CMSA 20 Garden Street, Cambridge, MA, United States

    During the 2021–22 academic year, the CMSA will be hosting a Colloquium, organized by Du Pei, Changji Xu, and Michael Simkin. It will take place on Wednesdays at 9:30am – 10:30am (Boston time). The […]

  • Langlands duality for 3 manifolds

    Virtual

    Speaker: David Jordan (U Edinburgh) Title: Langlands duality for 3 manifolds Abstract: Langlands duality began as a deep and still mysterious conjecture in number theory, before branching into a similarly deep and mysterious conjecture of […]

  • Strings, knots and quivers

    Virtual

    Speaker: Piotr Sułkowski (University of Warsaw) Title: Strings, knots and quivers Abstract: I will discuss a recently discovered relation between quivers and knots, as well as – more generally – toric Calabi-Yau […]
