Continuous families of properly infinite C*-algebras
Etienne Blanchard
Any unital separable continuous C(X)-algebra with properly infinite fibres is properly infinite as soon as the compact Hausdorff space X has finite topolog-ical dimension. We study…
Continuous fields of properly infinite C*-algebras
Etienne Blanchard
Any unital separable continuous C(X)-algebra with properly infinite fibres is properly infinite as soon as the compact Hausdorff space X has finite topological dimension. We study…
K_1-injectivity for properly infinite C*-algebras
Etienne Blanchard
One of the main tools to classify \cst-algebras is the study of its projections and its unitaries. It was proved by Cuntz in \cite{Cu81} that if is a \textit{purely infinite} s…
Extension of C*-bundles
Etienne Blanchard
Different (fibrewise) amalgamated products of continuous C*-bundles have been studied over the last years, one of the main question being to know when these amalgamated products ar…
Properly infinite C(X)-algebras and K_1-injectivity
Etienne Blanchard, Randi Rohde, Mikael Rordam
We investigate if a unital C(X)-algebra is properly infinite when all its fibres are properly infinite. We show that this question can be rephrased in several different ways, inclu…
Deformations of infinite projections
Etienne Blanchard
Let be a (semi-)continuous field of -algebras over a compact Hausdorff space and let be a projection in such that each is properly inf…
