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:Unitary extended topological field theories and higher Hermitian objects
DESCRIPTION:Colloquium \nSpeaker: Lukas Müller (LMU Munich) \nTitle: Unitary extended topological field theories and higher Hermitian objects \nAbstract: Mathematically\, topological field theories study the representation theory of manifolds undercutting and gluing. Extended topological field theories take this idea a step further by allowing one to cut manifolds in multiple directions\, leading to a formulation in terms of higher category theory. It is an open problem to give a complete definition and description of unitary representations of manifolds as extended topological field theories. \nIn my talk\, I will explain some recent progress towards the definition and classification of unitary extended topological field theories. This is based on a categorification of the concept of a Hermitian object in a rigid symmetric monoidal category\, introduced by Freed and Hopkins in the study of non-extended unitary topological field theories. \nThe talk is based on several joint works involving (in part) Giovanni Ferrer\, Brett Hungar\, Theo Johnson-Freyd\, Cameron Krulewski\, Nivedita\, David Penneys\, David Reutter\, Claudia Scheimbauer\, Luuk Stehouwer\, and Chetan Vuppulury\, as well as ongoing work with Theo Johnson-Freyd\, Cameron Krulewski\, and Luuk Stehouwer. \n  \n  \n\nTo subscribe or unsubscribe to the colloquium mailing list\, please visit this link.
