M-Theory Solutions in Multiple Signatures from E_11
arXiv:hep-th/0506122 · doi:10.1088/1126-6708/2005/12/041
Abstract
We generalise the previously given E_11 half BPS solution generating group element to general weights of A_10. We find that it leads to solutions of M-theory but in signatures (1,10), (2,9), (5,6), (6,5), (9,2) and (10,1). The signature transformations of the solution are naturally generated by the Weyl reflections required to transform the lowest A_10 weight into a general weight in the same representation. We also rediscover known S-brane solutions in M-theory from the group element in different signatures.
