Index Calculations for Convolution Type Operators

The talk deals with index formulas for convolution type operators on Lebesgue spaces over the real line. In general, such operators belong to the Banach algebras generated by the operators of multiplication by piecewise continuous and oscillating matrix functions and by the convolution operators with piecewise continuous and oscillating matrix symbols being Fourier multipliers.
