Algebras of Singular Integral Operators with Shifts and Oscillating Coefficients

The talk is devoted to the Fredholm theory of algebras of singular integral operators with coefficients admitting piecewise slowly oscillating discontinuities and with discrete subexponential groups of piecewise smooth shifts acting topologically free on Lebesgue spaces over composed contours. A general local method of studying the Fredholmness of nonlocal bounded linear operators on Banach spaces and the limit operators techniques are applied.
