Abstract: We expose recent results on a certain geometrical mechnism of formation of singularities of modified Novikov-Veselov and Davey-Stewartson II equations. The singular solutuions are constructed bymeans of surface theory. These systems are represented by L,A,B-triples and we discuss the relation of such a mechanism to the degeneration of the zero level discrete spectra of the correspondsing L-operators.
