We produce two tools for computing the K-theory of varieties with isolated singularities: Mayer-Vietoris sequences for open coverings and a Brown-Gersten spectral sequence.
## Abstract A criterion for the Fredholmness of singular integral operators with Carleman shift in __L~P~(Ξ__) is obtained, where Ξ is either the unit circle or the real line. The approach allows to consider unbounded coefficients in a class related to that of quasicontinuous functions. Application
## Abstract The paper is devoted to an application of a general local method of studying the Fredholmness of nonlocal bounded linear operators to Banach algebras of singular integral operators with piecewise continuous coefficients and discrete subexponential groups of piecewise smooth shifts actin
