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:A tale of two Lie groups
DESCRIPTION:Geometry and Mathematical Physics Seminar \nSpeaker: Spiro Karigiannis\, University of Waterloo \nTitle: A tale of two Lie groups \nAbstract: The classical Lie group SO(4) is well-known to possess a very rich structure\, relating in several ways to complex Euclidean spaces. This structure can be used to construct the classical twistor space Z over an oriented Riemannian 4-manifold M\, which is a 6-dimensional almost Hermitian manifold. Special geometric properties of Z are then related to the curvature of M\, an example of which is the celebrated Atiyah-Hitchin-Singer Theorem. The Lie group Spin(7) is a particular subgroup of SO(8) determined by a special 4-form. Inriguingly\, Spin(7) has several properties relating to complex Euclidean spaces which are direct analogues of SO(4) properties\, but sadly (or interestingly\, depending on your point of view) not all of them. I will give a leisurely introduction to both groups in parallel\, emphasizing the similarities and differences\, and show how we can nevertheless at least partially succeed in constructing a “twistor space” over an 8-dimensional manifold equipped with a torsion-free Spin(7)-structure. (I will define what those are.) This is joint work with Michael Albanese\, Lucía Martín-Merchán\, and Aleksandar Milivojevic. \n  \n
