"Infinite-Dimensional Symmetries: The Key to Understanding Gravity?"
11 Mar 2009, 14:00 – 15:00
(Living Reviews in Relativity Anniversary Lecture)
It is well known that the description of the non-gravitational interactions (electromagnetism, weak and strong nuclear forces) relies on finite-dimensional Lie groups and algebras (e.g., SU(3)X SU(2)X U(1)). Recently, it has been argued by many research teams that the description of the gravitational interaction should involve infinite-dimensional Lie algebras of hyperbolic Kac-Moody type, such as E(10). The talk will provide a brief, pedagogical introduction to these mathematical structures and present some of the evidence for their relevance to gravity.
