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:What is a self-concordant barrier function?\, and what is an accelerated first-order algorithm?  (ICM Series: On the work of Yurii Nesterov)
DESCRIPTION:CMSA Q&A Seminar \nSpeaker: Robert M. Freund\, MIT \nTitle: What is a self-concordant barrier function?\, and what is an accelerated first-order algorithm?  (ICM Series: On the work of Yurii Nesterov) \nAbstract: The two most impactful contributions of Nesterov on both theory and computation in optimization are (i) self-concordant barriers for interior-point methods in convex optimization\, and (ii) accelerated first-order methods for convex optimization. My own research in continuous optimization – and indeed my perspective on the field of mathematical optimization — has been profoundly impacted by Nesterov. In this talk I aim to explain these two contributions – self-concordant barriers and accelerated first-order methods – and how they have fundamentally improved optimization both computationally and theoretically. \n  \n  \n

SUMMARY:Math Science Lectures in Honor of Raoul Bott | Daniel Litt\, U Toronto
DESCRIPTION:Dates: October 19 & 21\, 2026 \nTime: 4:00–5:00 pm ET \nLocation: Science Center – Zimmer Hall Lecture Hall D\, 1 Oxford Street\, Cambridge MA & via Zoom Webinar \nIn-person registration \nWebinar Registration \n  \nSpeaker: Daniel Litt\, University of Toronto & Benedict H. Gross Distinguished Visitor\, Harvard Mathematics Department \nMonday\, October 19\, 2026 \nLecture 1: The arithmetic of differential equations \nAbstract: When does an algebraic differential equation have solutions which are themselves algebraic functions? This question goes back at least to Fuchs\, in 1875. Its conjectural answer\, due to Grothendieck and Katz in the linear case and Ekedahl-Shepherd-Barron-Taylor and Bost in general\, situates it as one of number theory. I’ll explain these conjectures and some progress towards them\, joint with Josh Lam\, for isomonodromy differential equations. This class of differential equations includes\, for example\, the Painlevé VI equation. This work is in part an excuse to study “motivic” aspects of the space of all algebraic differential equations. \n\nThe Monday lecture will be followed by a reception in the Math Dept Austine & Chilton McDonnell Common Room\, 4th floor \n  \nWednesday\, October 21\, 2026 \nLecture 2: Non-abelian motives \nAbstract: Non-abelian Hodge theory\, due to Corlette\, Simpson\, and others\, develops structures on the space of representations of the fundamental group of a complex variety analogous to the structures on its cohomology. Taking this analogy seriously\, we should expect *every* structure on cohomology to have an analogue in this “non-abelian” setting. I’ll discuss some work in this direction\, as well as a number of related conjectures and new structures whose “abelian” analogues are less clear. \n\n  \n\nHarvard Mathematics Professor Raoul Bott (1923 – 2005)\, was a Hungarian-American mathematician known for numerous foundational contributions to geometry in its broad sense. He is best known for his Bott periodicity theorem\, the Morse–Bott functions which he used in this context\, and the Borel–Bott–Weil theorem.
