The fare and commission audit expert system perf...

We first review the interpretation of world-sheet defects as D branes described by a critical theory in 11 dimensions, that we interpret asM theory. We then show thatD-brane recoil induces dynamically an anti-de-Sitter (AdS) space-time background, with criticality restored by a twelfth time-like dimension described by a Liouville field. Local physics in the bulk of this AdS11 may be described b...
