SUMMARY:CCMS Colloquium: Morse theory\, Floer homology\, and string topology (Ko Honda\, UCLA)
DESCRIPTION:CCMS Colloquium invites you to a talk by Professor Ko Honda\, Professor of Mathematics at UCLA. \nTitle: Morse theory\, Floer homology\, and string topology \nAbstract: One of the most important theories in geometry/topology is Floer homology\, which can be viewed as a Morse theory of a loop space of a manifold (a generalization of a surface to higher dimensions).  The aim of this talk is to give a gentle pictorial introduction to Morse theory for surfaces and then upgrade it in two steps: to Morse theory of loop spaces (e.g.\, of the 2-dimensional sphere) and then to “multiloops” (collections of many loops).  The last upgrade is intimately related to a mathematical model for string theory called “string topology”\, due to Chas-Sullivan\, and to quantum topology via the HOMFLY polynomial of knots/links. \nSpeaker Bio: Ko Honda is an entirely American-trained mathematician\, receiving his BA and MA from Harvard University in 1992 and PhD from Princeton University in 1997.  After postdocs/visiting positions at Duke\, the University of Georgia\, the American Institute of Mathematics\, and IHES\, he arrived in LA in 2001\, was a faculty member at USC for 12.5 years\, and then moved across town to UCLA\, where he has been for the last 11.5 years.  Sometime during his postdoc at Duke\, he discovered/invented an object called a “bypass” in contact geometry\, which allowed him to simplify the analysis of 3-dimensional contact manifolds and solve several open problems in that area\, some in joint work with Colin\, Etnyre\, and Giroux.  He has been working on contact and symplectic geometry ever since\, gradually branching out into adjacent areas (e.g.\, low-dimensional topology\, Floer theory\, and quantum topology) in the intervening years.

SUMMARY:CCMS Colloquium: Robert Cass (CMC)
DESCRIPTION:CCMS Colloquium invites you to a talk by Assistant Professor of Mathematics Robert Cass of Claremont McKenna College:\n\n \nTitle: An introduction to the Langlands program\n \nAbstract: Class field theory\, which was established in the early 20th century\, has its origins in Gauss’s law of quadratic reciprocity. As such\, it allows one to determine whether certain integer polynomials have a root mod p. The Langlands program is a vast area of current research in number theory that can be viewed as a generalization of class field theory to all integer polynomials. In this talk\, I will give a leisurely introduction to this circle of ideas by way of some concrete examples. I will conclude with my own work\, which includes a result on the independence of the cohomology theory chosen in a geometric and categorical analogue of the Langlands program.\n \nBrief Bio: Robert Cass joined the Mathematical Sciences Department at CMC as an Assistant Professor of Mathematics this fall. He received his B.S. from the University of Kentucky and his Ph.D. from Harvard University. After that\, he was an NSF postdoctoral fellow at Caltech and the University of Michigan. He is interested in the Langlands program and arithmetic geometry\, as well as related problems in algebraic geometry and representation theory. He enjoys mathematical questions that are simple to state but whose solutions involve tools from multiple disciplines\, especially those with unexpected connections to geometry.
