Supersymmetry, {ital p}-brane duality, and hidden spacetime dimensions
- Department of Physics and Astronomy, University of Southern California, Los Angeles, California 90089-0484 (United States)
A global superalgebra with 32 supercharges and all possible central extensions is studied in order to extract some general properties of duality and hidden dimensions in a theory that treats {ital p}-branes democratically. The maximal number of dimensions is 12, with signature (10,2), containing one space and one time dimension that are hidden from the point of view of perturbative ten-dimensional string theory or its compactifications. When the theory is compactified on {ital R}{sup {ital d}{minus}1,1}{circle_times}{ital T}{sup {ital c}+1,1} with {ital d}+{ital c}+2=12, there are isometry groups that relate to the hidden dimensions as well as to duality. Their combined intersecting classification schemes provide some properties of nonperturbative states and their couplings. {copyright} {ital 1996 The American Physical Society.}
