Exact Categories
Theo Buehler
We survey the basics of homological algebra in exact categories in the sense of Quillen. All diagram lemmas are proved directly from the axioms, notably the five lemma, the 3 x 3-l…

On the Duality between l^1-Homology and Bounded Cohomology
Theo Buehler
We modify the definition of l^1-homology and argue why our definition is more adequate than the classical one. While we cannot reconstruct the classical l^1-homology from the new d…

The Krein-Mil'man Theorem for Metric Spaces with a Convex Bicombing
Theo Buehler
We use bicombings on arcwise connected metric spaces to give definitions of convex sets and extremal points. These notions coincide with the customary ones in the classes of normed…
