I am quite confused about the terms topological K-theory, topological K-cohomology, etale K-theory, and topological K-homology. Is it the case that Thomason uses topological K-theory for what is otherwise called etale K-theory??? See his paper Riemann-Roch for algebraic vs topological K-theory, see maybe also modern papers by Rognes, Ausoni and maybe others.
