It is shown that the standard Gauss-Codazzi system of equations which
describe generic surfaces immersed into the three-dimensional Euclidea
n space is equivalent to the two-dimensional Dirac equation (Davey-Ste
wartson linear problem) accompanied by a specific constraint. It is de
monstrated that this system is linearizable via the parametrization of
the moving trihedral by the Euler angles. Some special classes of sur
faces are also considered.
