Abstract:
This text is concerned with the applicability of the finite section method to a certain type of operators on $L^\infty(R)$. These operators belong to the smallest closed algebra generated by convolution operators with symbol in the Wiener algebra and operators of multiplication by bounded functions with limits at plus and minus infinity. We use Banach algebra techniques to show that the finite section method is applicable to some operator $A$ in that algebra if and only if $A$ and an associated operator $\tilde A$ are invertible.
