Approximations of convolutions with almost periodic or
quasi-continuous symbol
We study the stability and Fredholm property of the finite
sections of convolution type
operators with semi-almost periodic and quasicontinuous
symbols, and operators of multiplication by slowly oscillating,
almost periodic or even more general coefficients. This is done by
introducing and exploring the notions of Rich sequences and
Quasi-Banded operators.
