CMSA New Technologies in Mathematics Seminar: Toolformer: Language Models Can Teach Themselves to Use Tools
SEMINARS, CMSA EVENTS
April 26, 2023 2:00 pmSpeaker: Timo Schick - Meta AI
Language models exhibit remarkable abilities to solve new tasks from just a few examples or textual instructions, especially at scale. They also, paradoxically, struggle with basic functionality, such as arithmetic or...

CMSA Colloquium: Boundary behavior at classical and quantum phase transitions
SEMINARS, CMSA EVENTS
April 26, 2023 12:30 pmSpeaker: Max Metlitski - MIT
There has been a lot of recent interest in the boundary behavior of materials. This interest is driven in part by the field of topological states of quantum matter, where...

Harvard-MIT Algebraic Geometry Seminar: Height moduli on algebraic stacks and counting families of varieties
SEMINARS, HARVARD-MIT ALGEBRAIC GEOMETRY
April 26, 2023 1:30 pmSpeaker: Jun-Yong Park - University of Melbourne
**Note special day, time & location** I will begin by reviewing the classical algorithm of Tate with some explicit polynomial calculations. Combining this with twisted stable maps theory leads us...

Mathematical Picture Language Seminar: Amenability and von Neumann algebras
MATHEMATICAL PICTURE LANGUAGE, SEMINARS
April 25, 2023 9:30 amSpeaker: Jesse Peterson - Vanderbilt University
Amenability for groups is a concept that was first introduced by von Neumann in 1929 to provide an explanation of the Banach-Tarski paradox. The concept has since been exported to...

Harvard–MIT Algebraic Geometry Seminar: Counting differentials with fixed residues
SEMINARS, HARVARD-MIT ALGEBRAIC GEOMETRY
April 25, 2023 3:00 pmSpeaker: Dawei Chen - Boston College
In this talk, we investigate meromorphic differentials on the Riemann sphere with a single zero and several poles of predetermined orders. Our aim is to determine the number of such...

CMSA Swampland Seminar: The Tameness of Quantum Field Theories
SEMINARS, CMSA EVENTS
April 24, 2023 11:00 amSpeaker: Thomas Grimm - Utrecht University
Tameness is a generalized notion of finiteness that is restricting the geometric complexity of sets and functions. The underlying mathematical foundation lies in tame geometry, which is built from o-minimal structures introduced in...

MIT-Harvard-MSR Combinatorics Seminar: Set-valued tableaux and enumeration of special chip configurations on graphs
SEMINARS, HARVARD-MIT COMBINATORICS
April 21, 2023 4:15 pmSpeaker: Nathan Pflueger - Amherst College
Chip-firing games on finite graphs provide a combinatorial analog of the theory of special divisors on algebraic curves. Each chip configuration determines two numbers: the degree and rank, analogous to...

Gauge Theory and Topology Seminar: The Dehn surgery characterisation of Whitehead doubles
Gauge Theory and Topology Seminar, SEMINARS
April 21, 2023 3:30 pmSpeaker: Laura Wakelin - Imperial College London
A slope p/q is said to be characterising for a knot K if the oriented homeomorphism type of the manifold obtained by performing Dehn surgery of slope p/q on K...

CMSA Quantum Matter in Mathematics and Physics: A model of the cuprates: from the pseudogap metal to d-wave superconductivity and charge order
SEMINARS, CMSA EVENTS
April 21, 2023 10:00 amSpeaker: Subir Sachdev - Harvard
Soon after the discovery of high temperature superconductivity in the cuprates, Anderson proposed a connection to quantum spin liquids. But observations since then have shown that the low temperature phase...
