Toeplitz Operators with Frequency Modulated Semi-Almost Periodic Symbols.
Mellin pseudodifferential operators with slowly varying symbols and singular integrals on Carleson curves with Muckenhoupt weights.
Discrete Wiener-Hopf operators on spaces with Muckenhoupt weight
The discrete Wiener-Hopf operator generated by a function with the Fourier series is the operator T(a) induced by the Toeplitz matrix on some weighted sequence space . We assume that w satisfies the Muckenhoupt condition and that a is a piecewise continuous function subject to some natural multiplier condition. The last condition is in particular satisfied if a is of bounded variation. Our main result is a Fredholm criterion and an index formula for T(a). It implies that the essential spectrum...
