Morita Equivalence and Interpolation of The Dirac-Born-infeld Theory on the Non-Commutative Torus
Pei Wang, Rui-Hong Yue, Kang-Jie Shi
In the noncommutative Dirac-Born-Infeld action with Chern-Simons term, an interpolation field is used in both DBI action and Chern-Simons term. The Morita equivalence is discus…

W-symmetries on the Homogeneous Space G/U(1)^r
Xiang-Mao Ding, Pei Wang
A construction of -symmetries is given only in terms of the nonlocal fields (parafermions ${\ps}_{\al}$), which take values on the homogeneous space , where is a s…
