In the paper it is proved that the property of singular integral operators with piecewise continuous coefficients to be Noetherian is stable with respect to their perturbation with certain non-compact operators. An example is constructed which demonstrates that the corner points of the contour of integration significantly affect the Noetherian property of singular operators with a shift. These results are obtained using the symbol of singular operators on contours with angular points, symbol, which is also determined in this paper. |
