On the derived category and $K$-functor of coherent sheaves on intersections of quadrics

A graded Clifford algebra connected with the complete intersection of several quadrics is considered. In terms of modules over this algebra, a description is given of the derived category of coherent sheaves and the Quillen $K$-functor of the intersection of quadrics, which generalizes the results of I. N. Bernshtein, I. M. Gel'fand, S. I. Gel'fand, and R. G. Swan. Here, ramified two-sheeted coverings of the parameter space arise in a natural way, the consideration of which is traditional for intersections of two or three quadrics.
