Novikov-Veselov Symmetries of the Two-Dimensional ( ) Sigma Model
We show that the Novikov-Veselov hierarchy provides a complete family of commuting symmetries of the two-dimensional ( ) sigma model. In the first part of the paper, we use these symmetries to prove that the Fermi spectral curve for the double-periodic sigma model is algebraic. Thus, our previous c...
