Topological B-model and image string theory Original Research Article

We study the topological B-model on a deformed image orbifolded conifold by investigating variation of complex structures via quantum Kodaira–Spencer theories. The fermionic/brane formulation together with systematic utilization of symmetries of the geometry gives rise to a free fermion realization of the amplitudes. We derive Ward identities which solve the perturbed free energy exactly. We also obtain the corresponding Kontsevich-like matrix model. All these confirm the recent conjecture on the connection of the theory with image type 0A string theory compactified at the radius image.
