Classical O(N) nonlinear sigma model on the half line: a study on consistent Hamiltonian description
Wenli He, Liu Zhao
The problem of consistent Hamiltonian structure for O(N) nonlinear sigma model in the presence of five different types of boundary conditions is considered in detail. For the case…
On open string in generic background
Liu Zhao, Wenli He
A set of consistent Poisson brackets for an open string in generic spacetime background and NS-NS -field is constructed. Upon quantization, this set of Poisson brackets lead to…
Boundary Poisson structure and quantization
Liu Zhao, Wenli He
A new approach for treating boundary Poisson structures based on causality and locality analysis is proposed for a single scalar field with boundary interaction. For the case of li…
The origin of noncommutativity?
Wenli He, Liu Zhao
Consistent boundary Poisson structures for open string theory coupled to background -field are considered using the new approach proposed in hep-th/0111005. It is found that the…
