A major effort is underway to translate it into pure mathematics. “There are … 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. For example, if we have an … Meer weergeven The equivariant algebraic K-theory is an algebraic K-theory associated to the category Meer weergeven There are a number of basic definitions of K-theory: two coming from topology and two from algebraic geometry.

Web11 mrt. 2024 · A Prüfer domain is just a generalization of a Dedekind domain in the non-Noetherian context. By definition, Prüfer domains are locally valuation rings. Of course, Noetherian Prüfer domains are Dedekind domains and vice versa. For example, the ring of integer-valued polynomials with rational coefficients is a Prüfer domain.
