Superstrings with new supersymmetry in (9,2) and (10,2) dimensions
Itzhak Bars, Cemsinan Deliduman
We construct superstring theories that obey the new supersymmetry algebra {Q_a , Q_b}=γ_{ab}^{mn} P_{1m} P_{2n}, in a Green-Schwarz formalism, with kappa supersymmetry also of the…
Duality Covariant Type IIB Supersymmetry and Nonperturbative Consequences
Itzhak Bars
Type-IIB supersymmetric theories have an SL(2,Z) invariance, known as U-duality, which controls the non-perturbative behavior of the theory. Under SL(2,Z) the supercharges are doub…
Strings and matrix models on genus g Riemann Surfaces
Itzhak Bars
This is a summary of old work on connections between discrete area preserving diffeomorphisms, reduced SU(N) Yang-Mills, strings, and the quantum Hall effect on a Riemann surface o…
String and Particle with Two Times
Itzhak Bars, Costas Kounnas
An action for a string and a particle with two timelike dimensions is proposed and analyzed. Due to new gauge symmetries and associated constraints, the motion of each system in th…
A case for 14 dimensions
Itzhak Bars
Extended superalgebras of types A,B,C, heterotic and type-I are all derived as solutions to a BPS equation in 14 dimensions with signature ( 11,3). The BPS equation as well as the…
Theories with Two Times
Itzhak Bars, Costas Kounnas
General considerations on the unification of A-type and B-type supersymmetries in the context of interacting p-branes strongly suggest that the signature of spacetime includes two…
