Note on Gauge Theory on Fuzzy Supersphere
Satoshi Iso, Hiroshi Umetsu
We construct a supermatrix model whose classical background gives two-dimensional noncommutative supersphere. Quantum fluctuations around it give the supersymmetric gauge theories…
Ginsparg-Wilson Relation and 't Hooft-Polyakov Monopole on Fuzzy 2-Sphere
Hajime Aoki, Satoshi Iso, Keiichi Nagao
We investigate several properties of Ginsparg-Wilson fermion on fuzzy 2-sphere. We first examine chiral anomaly up to the second order of the gauge field and show that it is indeed…
Gauge Theory on Noncommutative Supersphere from Supermatrix Model
Satoshi Iso, Hiroshi Umetsu
We construct a supermatrix model which has a classical solution representing the noncommutative (fuzzy) two-supersphere. Expanding supermatrices around the classical background, we…
Noncommutative Superspace, Supermatrix and Lowest Landau Level
Machiko Hatsuda, Satoshi Iso, Hiroshi Umetsu
By using graded (super) Lie algebras, we can construct noncommutative superspace on curved homogeneous manifolds. In this paper, we take a flat limit to obtain flat noncommutative…
