Comments on D-Brane and Enhanced Symmetry in Type II String
H. B. Gao
We propose a configuration of D-branes welded by analogous orbifold operation to be responsible for the enhancement of gauge symmetry in type II string compactified on the…
On the sine-Gordon--Thirring equivalence in the presence of a boundary
Z-M Sheng, H-B Gao
In this paper, the relationship between the sine-Gordon model with an integrable boundary condition and the Thirring model with boundary is discussed and the reflection -matrix…
More Dual String Pairs From Orbifolding
H. B. Gao
We construct more dual pairs of type II-heterotic strings in four dimensions with spacetime supersymmetry. On the type II side the construction utilizes the various possibl…
Some Features of Blown-Up Nonlinear -Models
H. B. Gao, H. Römer
In terms of the gauged nonlinear -models, we describe some results and implications of solving the following problem: Given a smooth symplectic manifold as target space with a q…
Gauging and symplectic blowing up in nonlinear sigma-models: I. point singularities
H. B. Gao, H. Römer
In this paper a two dimensional non-linear sigma model with a general symplectic manifold with isometry as target space is used to study symplectic blowing up of a point singularit…
