A groupoid approach to the equivariant coarse Baum--Connes conjecture

In this paper, we develop a groupoid approach to the equivariant coarse Baum--Connes conjecture. For a bounded geometry metric space $X$ equipped with a proper, free, and isometric action of a...

Sums of two symbols in $K_2(F)/2K_2(F)$ in characteristic two

In this paper, study sums $A=\{a,b\}_2 \{c,d\}_2$ of two symbols in $K_2(F)/2K_2(F)$ when $\operatorname{char}(F)=2$. We first prove a chain lemma that connects $A$ to...

An Euler Characteristic for Unbounded Chain Complexes

We propose a definition of an Euler characteristic for unbounded chain complexes by taking the (usual) Euler characteristics of successively longer parts of the complex, weighted inversely...
