We analyze Givental's symplectic loop space formalism in the context of B-model geometry on Calabi-Yau manifolds, and explain the Fock space construction via the renormalization techniques of gauge theory. We also give a physics interpretation of the Virasoro constraints as the symmetry of the classical BCOV action functional, and discuss the Virasoro constraints in the quantum theory. %K BCOV %K Calabi-Yau %K renormalization %K mirror symmetry %U http://dx.doi.org/10.3842/SIGMA.2012.101
