K-theory

Definition

K-theory is a branch of mathematics that deals with the study of vector bundles and is used in various fields, including algebraic topology and differential geometry. It provides a framework to understand the properties of spaces through the lens of algebraic structures, linking topology with abstract algebraic concepts. In the context of turbulent fluxes, k-theory can help in understanding the statistical properties of turbulence and how energy and momentum are transferred in turbulent flows.
