DESCRIPTION:Title: <a href="https://researchseminars.org/talk/tandg/21/">D
 eformation classes of invertible field theories and the Freed–Hopkins co
 njecture</a>\nby Dan Grady (Wichita State University) as part of Topology 
 and Geometry Seminar (Texas\, Kansas)\n\n\nAbstract\nIn their seminal work
 \, Freed and Hopkins studied the moduli space of topological\, reflection 
 positive\, invertible\, Euclidean field theories\, providing a complete cl
 assification in terms of certain objects arising in stable homotopy theory
 .  In this work\, it was also conjectured that a similar classification ho
 lds in the case of nontopological field theories\, and this conjecture is 
 already being used in a variety of applications to condensed matter physic
 s.  In this talk\, I will discuss a recent result which provides an affirm
 ative answer to this conjecture.  I will begin by reviewing motivation and
  background on reflection positive theories.  Then I will state the conjec
 ture and sketch of the proof.\n
