Gauge theories on noncommutative and BPS-like equations
Akifumi Sako, Toshiya Suzuki, Hiroshi Umetsu
We give the Fock representation of a noncommutative and gauge theories on it. The Fock representation is constructed based on star products given by deformation qua…
Gauge Theories in Noncommutative Homogeneous Kähler Manifolds
Yoshiaki Maeda, Akifumi Sako, Toshiya Suzuki +1
We construct a gauge theory on a noncommutative homogeneous Kähler manifold, where we employ the deformation quantization with separation of variables for Kähler manifolds formulat…
Explicit Formulae for Noncommutative Deformations of CP^N and CH^N
Akifumi Sako, Toshiya Suzuki, Hiroshi Umetsu
We give explicit expressions of a deformation quantization with separation of variables for CP^N and CH^N. This quantization method is one of the ways to perform a deformation quan…
Dimensional Reduction of Seiberg-Witten Monopole Equations, N=2 Noncommutative Supersymmetric Field Theories and Young Diagrams
Akifumi Sako, Toshiya Suzuki
We investigate the Seiberg-Witten monopole equations on noncommutative(N.C.) R^4 at the large N.C. parameter limit, in terms of the equivariant cohomology. In other words, N}=2 sup…
Partition functions of Supersymmetric Gauge Theories in Noncommutative R^{2D} and their Unified Perspective
Akifumi Sako, Toshiya Suzuki
We investigate cohomological gauge theories in noncommutative R^{2D}. We show that vacuum expectation values of the theories do not depend on noncommutative parameters, and the lar…
Recovery of Full N=1 Supersymmetry in Non(anti-)commutative Superspace
Akifumi Sako, Toshiya Suzuki
We investigate SUSY of Wess-Zumino models in non(anti-)commutative Euclidean superspaces. Non(anti-)commutative deformations break 1/2 SUSY, then non(anti-)commutative Wess-Zumino…
PST-type SL(2;R)-covariant Super D3-brane Action in Flat Spacetime
Toshiya Suzuki
We give an explicit form of the PST-type SL(2;R)-covariant super D3-brane action for the flat Minkowski background. To this end, we follow the prescription developed by Hatsuda and…
Ring Structure of SUSY * Product and 1/2 SUSY Wess-Zumino Model
Akifumi Sako, Toshiya Suzuki
There are two types of non(anti-)commutative deformation of D=4, N=1 supersymmetric field theories and D=2, N=2 theories. One is based on the non-supersymmetric star product and th…
Supersymmetric Action of SL(2;Z)-covariant D3-brane and its Kappa-symmetry
Toshiya Suzuki
We consider a supersymmetric extension of the SL(2;Z)-covariant D3-brane action proposed by Nurmagambetov, and prove its kappa-symmetry in an on-shell type-IIB supergravity backgro…
BPS Analysis of the Charged Soliton Solutions of D-brane Worldvolume Theory from the Viewpoint of Target-space Supersymmetry
Toshiya Suzuki
We investigate BPS properties of the charged soliton solutions of D-brane worldvolume theory, which is described by the supersymmetric Dirac-Born-Infeld action, by means of the N=2…
Loop Equations for + and - Loops in c = 1/2 Non-Critical String Theory
Ryuichi Nakayama, Toshiya Suzuki
New loop equations for all genera in non-critical string theory are constructed. Our loop equations include two types of loops, loops with all Ising spins up (+ l…
Integrability of Schwinger-Dyson Equations in 2D Quantum Gravity and c < 1 Non-critical String Field Theory
Ryuichi Nakayama, Toshiya Suzuki
We investigate the integrability of the Schwinger-Dyson equations in string field theory which were proposed by Ikehara et al as the continuum limit of t…
