K-theory math
In mathematics, K-theory is, roughly speaking, the study of a ring generated by vector bundles over a topological space or scheme. In algebraic topology, it is a cohomology theory known as topological K-theory. In algebra and algebraic geometry, it is referred to as algebraic K-theory. It is also a … Meer weergeven The Grothendieck completion of an abelian monoid into an abelian group is a necessary ingredient for defining K-theory since all definitions start by constructing an abelian monoid from a suitable category … Meer weergeven The other historical origin of algebraic K-theory was the work of J. H. C. Whitehead and others on what later became known as Meer weergeven Virtual bundles One useful application of the Grothendieck-group is to define virtual vector bundles.
