Non-commutative Field Theory on S^4
Ryuichi Nakayama, Yusuke Shimono
In the previous paper (hep-th/0402010) we proposed a matrix configuration for a non-commutative S^4 (NC4S) and constructed a non-commutative (star) product for field theories on NC…

Matrix Configurations for Spherical 4-branes and Non-commutative Structures on S^4
Ryuichi Nakayama, Yusuke Shimono
We present a Matrix theory action and Matrix configurations for spherical 4-branes. The dimension of the representations is given by N=2(2j+1) (j=1/2,1,3/2,...). The algebra which…
