K-theory spectrum

K-theory is a branch of mathematics that deals with the study of vector bundles and their generalizations in the context of topology and algebra. One of the important structures in K-theory is the **K-theory spectrum**. In a more formal sense, a K-theory spectrum is a spectrum in stable homotopy theory that encodes information about vector bundles over topological spaces. It provides a way to define K-theory in a homotopical framework.
