Computation and Homotopical Applications of Induced Crossed Modules
We explain how the computation of induced crossed modules allows the
computation of certain homotopy 2-types and, in particular, second homotopy
groups. We discuss various issues involved in computing induced crossed modules
and give some examples and applications.Comment: 15 pages, xypic, latex2
Spectral morphisms, K-theory, and stable ranks
We give a brief account of the interplay between spectral morphisms,
K-theory, and stable ranks in the context of Banach algebras.Comment: 12 pages; to appear in the Proceedings of the Workshop on
Noncommutative Geometry (Fields Institute, Toronto 2008
