Abstract

For a one-parameter family of Calabi-Yau d-fold M embedded in CPd+1{{CP}^{d+1}}, we consider a new quasi-topological field theory A{A^{\ast}}(M)-model compared with the AA(M)-model. The two point correlators on the sigma model moduli space (the hermitian metrics) are analyzed by the AAA{A^{\ast}}-fusion on the world sheet sphere. A set of equations of these correlators turns out to be a non-affine A-type Toda equation system for the d-fold M. This non-affine property originates in the vanishing first Chern class of M. Using the results of the AAA{A^{\ast}}-equation, we obtain a genus one partition function of the sigma model associated to the M in the recipe of the holomorphic anomaly. By taking an asymmetrical limit of the complexified {\kae} parameters tˉ{\bar{t}\rightarrow \infty} and tt is fixed, the A{A^{\ast}}(M)-model part is decoupled and we can obtain a partition function (or one point function of the operator O(1){{\cal O}^{(1)}} associated to a {\kae} form of M) of the AA(M)-matter coupled with the topological gravity at the stringy one loop level. The coefficients of the series expansion with respect to an indeterminate q:=e2πitq:={e^{2\pi i t}} are integrals of the top Chern class of the vector bundle {\Large ν\nu } over the moduli space of stable maps with definite degrees.
