Abstract:
This is a joint work with Jean Savinien, which appeared in Erg. Th. Dyn.
Syst., 29, (2009), 997--1031.)
A spectral sequence is proposed to compute the $K$-groups of a crossed
product $A\rtimes{\mathbb Z}^d$ by a ${\mathbb Z}^d$-action. This spectral
sequence generalizes the Pimsner-Voiculescu exact sequence when $d>1$. It
is also dual to the Atiyah-Hirzebruch spectral sequence for CW-complexes.
The construction applies to the computation of the K-groups of a tiling
space.
