Integrable boundary interaction in 3D target space: the "pillow-brane" model

arXiv:1208.5259 · doi:10.1016/j.nuclphysb.2013.05.008

Abstract

We propose a model of boundary interaction, with three-dimensional target space, and the boundary values of the field {\vec X}\in R^3 constrained to lay on a two-dimensional surface of the "pillow" shape. We argue that the model is integrable, and suggest that its exact solution is described in terms of certain linear ordinary differential equation.
