Please join us on Friday, August 13, 2010 as Ryan Reich of Harvard University will be giving a lecture on Beilinson’s “How to glue perverse sheaves.” We will be serving coffee, tea, and cookies starting at 3:30pm and the lecture will begin at 4:00pm. The lecture will be held in our studio classroom at 929 Massachusetts Avenue Suite #102 in Cambridge. The abstract is listed below and we look forward to seeing you!
Abstract: The titular, foundational work of Beilinson not only gives a technique for gluing perverse sheaves but also implicitly contains constructions of the nearby and vanishing cycles functors of perverse sheaves. These constructions are completely elementary and show that these functors preserve perversity and respect Verdier duality on perverse sheaves. The work also defines a new, “maximal extension” functor, which is left mysterious aside from its role in the gluing theorem. In this talk, we will attempt to clarify some of these notions and results, and present details of some of the constructions and theorems.
The Worldwide Center of Mathematics (www.centerofmath.org) is located midway between Harvard and Central Squares, at 929 Massachusetts Avenue, Cambridge, MA, in Suite #102. Travel to the Center by public transportation is easy via the #1 bus, or by taking the subway (the T) to Central Square, and walking for 10 minutes. Suite #102 is located on floor 01.
All attendees will need to sign a release form, as the lecture will be recorded for distribution on the Web.
