The two-parameter brane σ -model and extended solutions of M -theory
Abstract
Abstract We investigate two-parameter solutions of σ -models on two dimensional symmetric spaces contained in E 11 . The σ -models considered here are not proposed as fundamental two-dimensional quantum field theories, but as auxiliary, solution-generating constructions extending the one-parameter brane σ -model framework. Embedding such σ -model solutions in space-time gives classical bosonic solutions of M ∗ - and M ′ -theory whose warp factors are travelling wavefunctions solving a transverse wave equation, rather than the harmonic functions appearing in the standard one-parameter brane solutions. Weyl reflection allows such solutions to be mapped to M -theory solutions where the wave functions depend explicitly on extra coordinates contained in the fundamental representation of E 11 .
