Abstract
A discrete generalization of the sine-Gordon equation on a lattice is studied. The corresponding Bäcklund transformations, soliton solutions, action principle, conservation laws, and inverse scattering equations are obtained. The connection to a discrete version of the two-dimensional nonlinear σ model is found.
