In the definition of the symbol function, there are involved numbers characterizing the space in which the research is carried out, as well as the values of the corner points of the contour, which makes it possible to obtain formulas for calculating the essential norms of singular operators and conditions for the solvability of singular equations with a shift.ensingular operatorBanach algebraspiecewise Lyapunov contoursymbolNoether conditionsArticle
