This work is devoted to the study of the foundations of quantum -theory, a -theoretic version of quantum cohomology theory. In particular, it gives a deformation of the ordinary -ring of a smooth projective variety , analogous to the relation between quantum cohomology and ordinary cohomology. This new quantum product also gives a new class of Frobenius manifolds.
