 | Wu, Yong-Shi | Nonlinear Ŵ∞ current algebra in the SL(2,R)/U(1) coset model | We show that in the world-sheet SL(2,R)/U(l) coset model there exists a hidden nonlinear W∞ current algebra, which incorporates all higher-spin (s≥ 2) currents including the energy-momentum tensor. Our proof is based on a free-field realization of Woo in terms of two scalars, as well as an ele... | W-algebras; Coset model; World-sheet; String theory; Spacetime; Quantum currents | 1992-05 |

 | Wu, Yong-Shi | Moyal representation of the string field star product in the presence of a B background | In this paper we show that in the presence of an antisymmetric tensor B background, Witten's star algebra for open string fields persists to possess the structure of a direct product of commuting Moyal pairs. The interplay between the noncommutativity due to three-string overlap and that due to the ... | String theory; Moyal pairs; Moyal structure; Noncommutativity | 2003-06 |

 | Wu, Yong-Shi | Type-IIB-string-M-theory duality and longitudinal membranes in M(atrix) theory | In this paper we study duality properties of the M(atrix) theory compactified on a circle. We present evidence for the equivalence of this theory to the strong coupling limit of type-IIB string theory compactified on a circle. In the M(atrix) theory context, our evidence for this duality consists of... | Matrix theory; Longitudinal membranes; Compactification; String theory; Duality | 1998-02 |

 | Wu, Yong-Shi | Absence of (1,0) supersymmetry anomaly in world-sheet gauge theories: a purely cohomological proof | A purely cohomological proof is given for the absence of the (1,0) supersymmetry anomaly in gauge theories on a world sheet. In particular, it is shown that generalized cohomological approaches to anomalies in supersymmetric gauge theory, either formulated in whole superconnection space or only in t... | World sheet; String theory; Superfields; Superspace | 1989-01 |

 | Wu, Yong-Shi | Chiral bosonization and local Lorentz-invariant actions for chiral bosons | We formulate a geometrical theory of self-dual scalar fields in two dimensions with a local Lorentz-invariant action. Path-integral quantization is used to derive chiral bosonization by demonstrating equivalence of correlation functions of currents and energy-momentum tensors in our theory with thos... | Bosonization; String theory; Weyl fermions | 1988-06 |

 | Wu, Yong-Shi | Holography and noncommutative Yang-Mills theory | In this Letter a recently proposed gravity dual of noncommutative Yang-Mills theory is derived from the relations between closed string moduli and open string moduli recently suggested by Seiberg and Witten. The only new input one needs is a simple form of the running string tension as a function ... | Noncommutativity; String theory; Gravity dual | 2000-03 |
