Summary: I generalize the notion of composition of algebraic correspondences using the refined Gysin homorphism of Fulton-MacPherson intersection theory. Using this notion, I give a short self-contained proof of Rost's "nilpotence theorem" and a generalization of one important proposition used by Rost in his proof of the theorem.
