The paper discusses integrable systems in dimension (2+1) associated with the Lax pair operators in the form \(L=\partial_x\partial_y +G\partial_y + S\) and \(H=\partial_x^2+\partial_y^2+F\partial_y +A\) (the so-called GKMMN systems) and the related problems such as real reductions, reductions to the 2D-Burgers hierarchies, structure of the manifold of the Bloch-Floquet eigenfunctions, and associated algebro-geometric inverse spectral problems.
