First of all we must decide what it means for a C ∗ -algebra to be KK-contractible, i.e., KK-equivalent to 0. We do this first for E-theory in Section 2 and then modify the approach

The boundary construction method was used for all divisible tilings for which K > 12 since in this case we are guaranteed that the tiling has no free vertices and hence there

To complete the proof of the lemma we need to obtain a similar estimate for the second integral on the RHS of (2.33).. Hence we need to concern ourselves with the second integral on

If one chooses a sequence of models from this family such that the vertices become uniformly distributed on the metrized graph, then the i th largest eigenvalue of the

In [RS1] the authors study crossed product C ∗ –algebras arising from certain group actions on ˜ A 2 -buildings and show that they are generated by two families of partial

The construction of homogeneous statistical solutions in [VF1], [VF2] is based on Galerkin approximations of measures that are supported by divergence free periodic vector fields

Although the choice of the state spaces is free in principle, some restrictions appear in Riemann geometry: Because Einstein‘s field equations contain the second derivatives of the
