An Index Formula for Toeplitz Operators with Oscillating Symbols
The talk is devoted to calculating the indices of Toeplitz
operators with oscillating matrix symbols on the Hardy space over
the upper half-plane. The symbols belong to the -algebra
generated by semi-almost periodic and slowly oscillating matrix
functions. An approach which does not use the harmonic extensions
of slowly oscillating matrix functions is presented.
