Quantum Cohomology and Closed-String Mirror Symmetry for Toric Varieties
Abstract We give a short new computation of the quantum cohomology of an arbitrary smooth (semiprojective) toric variety $X$, by showing directly that the Kodairaā€“Spencer map of Fukayaā€“Ohā€“Ohtaā€“Ono defines an isomorphism onto a suitable Jacobian ring. In contrast to previous results of this kind, $X$ need not be compact. The ā€¦
