Brane sigma models and solutions in M, Mstar, and Mprime theories
Sarben Sarkar
(King's)
Abstract:
I discuss one and two-parameter solutions of sigma models on
symmetric spaces contained in E11. Embedding one-parameter
sigma model solutions in space-time give a metric which
depends on harmonic functions typical in general relativity,
supergravity and M-theory. Embedding two-parameter sigma
model solutions in space-time give a metric which depends on
general travelling wave functions in M* and M’-theory
(theories which have space-time signatures with more than
one time). Weyl reflection allows the latter solutions to be
mapped to M-theory solutions where the wave functions
depend explicitly on extra co-ordinates contained in the
fundamental representation of E11. I will also give an example of two-time physics realisable in the laboratory
