SUMMARY:Lagrangian Floer Theory and Applications Program
DESCRIPTION:Lagrangian Floer theory and Applications Program \nDates: September 15–November 21\, 2026 \nLocation: CMSA G10\, 20 Garden St.\, Cambridge MA 02138 \nThis thematic program will focus on recent developments in Lagrangian Floer theory and applications.  These include the development of family Floer theory\, degeneration techniques\, Floer homotopy theory in the Lagrangian case\, Floer theory in prime characteristic\, and applications to problems in singularity theory\, geometry and dynamics. \nA one-week workshop will be held near the start of the program (September 28 – October 2\, 2026)\, with the same title as the thematic program. \nOrganizers: Denis Auroux (Harvard)\, Jonny Evans (Lancaster)\, and Chris Woodward (Rutgers) \n  \nTo express interest in attending the workshop or program\, and to apply for funding if available\, please fill out the form.  \nFunding from the National Science Foundation may be available for US-based graduate students and postdoctoral fellows. \n  \n \nimage: Water Sky Garden\, Vancouver\nDate: 31 January 2010\, 12:57:46\nSource: Studio Echelman\nAuthor: Peter Vanderwarker\, Studio Echelman \n

SUMMARY:Can Math Mend a Broken Heart?
DESCRIPTION:CMSA Q&A Seminar \nSpeaker: Wes Cain\, Harvard \nTitle: Can Math Mend a Broken Heart? \nAbstract: I will discuss an abnormal cardiac rhythm known as T-wave alternans\, and a simple feedback control method (time-delay autosynchronization\, TDAS) that has been used successfully to suppress alternans experimentally. Variants of TDAS have been used for chaos control and prevention of period-doubling bifurcation in physical systems. I will explain how basic ideas from dynamical systems (e.g.\, the contraction mapping principle and Lyapunov functions) can be used to explore the robustness of TDAS. \n  \n

SUMMARY:On the emergence of representational geometry from the statistics of natural language
DESCRIPTION:New Technologies in Mathematics Seminar \nSpeaker: Yasaman Bahri (Google DeepMind) \nTitle: On the emergence of representational geometry from the statistics of natural language \nAbstract: Large language models organize their internal representations into rich geometric structures that mirror the concepts of natural language. For example\, categorical concepts often map to linear directions\, while words and phrases having a notion of space or time trace out winding manifolds. Remarkably\, these geometries emerge across diverse settings despite differences in neural architecture and training algorithms. Further\, this representational structure is key to understanding how models perform computations. What is the origin of this universal geometry? We turn to simpler models of language — classic word embedding methods — to shed light on this question. We develop a theoretical framework for the co-occurrence statistics of natural language whose predictions show striking agreement with empirical findings. Our work provides a unified explanation for prior observations of representational geometry and a rigorous foundation for further theoretical development.
