### The K-Theory of Vector bundles with Endomorphisms over a Scheme, by Dongyuan Yao

We give a description of the K-theory of the category of vector bundles with
endomorphisms over a scheme, which generalizes those of D. Grayson when the
scheme is affine. Then we give an example showing that the Mayer-Vietoris
sequence does not hold for the K-theory of vector bundles with endomorphisms,
which indicates that the K-theory of vector bundles with endomorphisms is a
global theory (not determined by local data).
