Pseudoduality and Conserved Currents in Sigma Models
arXiv:0704.3605 · doi:10.1142/S021773230902876X
Abstract
We discuss the current conservation laws in sigma models based on a compact Lie groups of the same dimensionality and connected to each other via pseudoduality transformations in two dimensions. We show that pseudoduality transformations induce an infinite number of nonlocal conserved currents on the pseudodual manifold.
