QUADRATIC FUNCTORS AND METASTABLE HOMOTOPY

[摘要] Quadratic functors lead to the fundamental notion of a quadratic R-module M where R is a ringoid or a ring. We introduce the quadratic tenser product A circle times (R) M and the corresponding abelian group Hom (R)(A, M) consisting of quadratic forms. Then we describe new quadratic derived functors of circle times and Horn together with applications for homotopy groups of Moore spaces and (co)homology groups of Eilenberg-Mac Lane spaces.
