  • In this thesis, we present expositions of Gromov-Witten invariants, Hurwitz numbers, topological recursion and their connections. By remodeling theory, open Gromov-Witten invariants of C^3 and C^3/Z_a satisfy the topological recursion of Eynard-Orantin defined on framed mirror curve of toric Calabi-Yau three orbifold target spaces. Studies show that simple/orbifold Hurwitz numbers can be obtained using topological recursion with spectral curve given by Lambert/a-Lambert curve. Also, both the open Gromov-Witten invariants of toric Calabi-Yau three orbifold and the simple and double Hurwitz numbers can be formulated via Hodge integrals. We extend these connections by determining the relationship between the open Gromov-Witten invariants of C^3/Z_a (with insertions of orbifold cohomology classes) and the full double Hurwitz numbers through referring to their Hodge integral formulations and to orbifold Riemann-Roch formula. By remodeling theory and mirror theorem for disk potentials, we make a conjecture relating a specific type of double Hurwitz numbers H_g(ν(γ, 2), μ) and topological recursion. We predict that these double Hurwitz numbers H_g(ν(γ, 2), μ) can be generated using topological recursion defined on the spectral curve ye^{−2y} − τxe^{−y} + x^2 = 0.
