A Fundamental Theorem for the -theory of connective -algebras

Ernest E. Fontes, Crichton Ogle

Invoking the density argument of Dundas-Goodwillie-McCarthy, we extend the Fundamental Theorem of -theory from the category of simplicial rings to the category of -a…

Fundamental theorems for the K-theory of -algebras, I: the connective case

Crichton Ogle

We extend the Bass-Quillen Fundamental Theorem of Algebraic K-theory to the Waldhausen K-theory of connective -algebras. The same technique used in this extension also yie…

Subexponential group cohomology and the K-theory of Lafforgue's algebra A_{max}(pi)

R. Ji, C. Ogle

We show that for any finitely generated group G, group cohomology classes represented by cocycles of subexponential growth are extendable over the topological K-groups of the Laffo…

On the homotopy type of A(Σ(X))

C. Ogle

We give a correct proof that for all connected spaces X, the functor X |-> A(Σ(X)) splits up to homotopy as a product of its Goodwillie derivatives.

Filtrations of simplicial functors and the Novikov Conjecture

Crichton Ogle

We show that the Strong Novikov Conjecture for the maximal C*-algebra C*(G) of a discrete group G is equivalent to a statement in topological K-theory for which the corresponding s…

Polynomially bounded cohomology and discrete groups

Crichton Ogle

We establish the homological foundations for studying polynomially bounded group cohomology, and show that the natural map from PH^*(G;Q) to H^*(G;Q) is an isomorphism for a certai…
