0. Introduction 0.1. Quantum cohomology. Quantum cohomology of a projective algebraic manifold V is a formal deformation of its cohomology ring. Parameters of this deformation are coordinates on the space H * (V), and the structure constants are the third derivatives of a formal series Φ V (potential, or free energy) whose coefficients count the number of parametrized rational curves on V with appropriate incidence conditions (see [KM] for details). A natural problem arises how to calculate Φ V… CONTINUE READING
