- This thesis studies Frobenius manifolds arising from extended deformations of complex structures on compact Calabi-Yau manifolds, following the construction by Sergey Barannikov and Maxim Kontsevich. The work is based on the investigation of formal moduli spaces of solutions to the Maurer-Cartan equations modulo gauge equivalence. We provide a foundational overview of deformation theory from the perspective of differential geometry and prove the equivalence between gauge-equivalent deformations and isomorphic deformations. Based on this framework, we construct a differential Gerstenhaber-Batalin-Vilkovisky (dGBV) algebra associated to the deformation of Calabi-Yau manifolds and then construct the corresponding Frobenius manifold.
