We prove that the moduli space of the pseudo holomorphic curves in the
A-model on a symplectic torus is homeomorphic to a moduli space of Feynman
diagrams in the configuration space of the morphisms in the B-model on the
corresponding elliptic curve. These moduli spaces determine the $A_{\infty}$
structure of the both models.Comment: 21 pages, 8 figure
