DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/78/">I
 IB Determined</a>\nby Jonathan Heckman (University of Pennsylvania) as par
 t of NHETC Seminar\n\n\nAbstract\nWe use the Swampland Cobordism Conjectur
 e recently proposed by McNamara and Vafa to study the spectrum of objects 
 in type IIB string theory. A famous feature of type IIB string theory (as 
 well as many quantum systems) is that it enjoys a non-abelian duality grou
 p. By computing the relevant cobordism groups\, we show that the cobordism
  conjecture successfully reconstructs many known supersymmetric objects\, 
 and also predicts the existence of a new non-supersymmetric "reflection 7-
 brane\," the properties of which we describe. Based on joint work with Deb
 ray\, Dierigl\, Montero and Torres.\n
