Speaker: Dr. Ingmar Saberi (CAS Researcher in Residence/Physics, LMU)
Respondent: Dr. Axel Kleinschmidt (MPI for Gravitational Physics, Potsdam)
Since its discovery by Cremmer, Julia, and Scherk in 1978, eleven-dimensional supergravity has been a long-standing object of fascination in theoretical physics. It is the unique supergravity theory in eleven dimensions, which is the largest possible dimension in which a supergravity theory can exist; although it is related to the supergravity limit of every known string theory model, the expected completion of the theory to the long-sought “M-theory” remains devoid of any concrete description. Expectations suggest that the theory should arise, in analogy to string theory, by a first-quantized theory of dynamical surfaces called “membranes,“ but no satisfactory construction, whether along these or other lines, has been given.
Ingmar Saberi will talk about eleven-dimensional super gravitation, applying the newest results from the theory of pure spinor superfields.
The Center for Advanced Studies at LMU provides a forum for scientific exchange and discussion that bridges the divide between the established disciplines. Its activities are designed to promote all forms of collaborative research and to stimulate interdisciplinary communication within the University. In addition, it facilitates the integration of visiting scholars and scientists into the academic life of the University.
