Orientifolded Matrices and Supersymmetries that Give Rise to Spacetime Directional Asymmetry of Effective Interactions
Hiroshi Itoyama, Reiji Yoshioka
Effects of matrix orientifolding that preserves supersymmetries are considered in the IIB matrix model with regard to its effective dynamics generated for diagonal elements. Taking…
Nambu-Goto Like Action for the AdS_5 x S^5 Superstrings in the Generalized Light-Cone Gauge
Hiroshi Itoyama, Takeshi Oota, Reiji Yoshioka
We reinvestigate the kappa-symmetry-fixed Green-Schwarz action in the AdS_5 x S^5 background in a version of the light-cone gauge. In the generalized light-cone gauge, the action h…
Partition Functions of Reduced Matrix Models with Classical Gauge Groups
H. Itoyama, H. Kihara, R. Yoshioka
We evaluate partition functions of matrix models which are given by topologically twisted and dimensionally reduced actions of d=4 N=1 super Yang-Mills theories with classical (sem…
Matrix Orientifolding and Models with Four or Eight Supercharges
Hiroshi Itoyama, Reiji Yoshioka
The conditions under which matrix orientifolding and supersymmetry transformations commute are known to be stringent. Here we present the cases possessing four or eight supercharge…
