Query: Corrugated surfaces with slow modulation and quasiclassical Weierstrass
  representation   Quasiclassical generalized Weierstrass representation for highly corrugated
surfaces with slow modulation in the three-dimensional space is proposed.
Integrable deformations of such surfaces are described by the dispersionless
Veselov-Novikov hierarchy.
