Abstract

We propose a definition of the category Momult(P)\mathit{Mo}^{\mathrm{mult}}(P) of multi-valued Morse homotopy on PP consisting of multi-valued functions associated to Lagrangian multi-sections. We then show that a full subcategory MoEmult(P)\mathit{Mo}^{\mathrm{mult}}_{\mathcal{E}}(P) of Momult(P)\mathit{Mo}^{\mathrm{mult}}(P) is AA_\infty-equivalent to a full subcategory DGEvect(CP2)\mathit{DG}_{\mathcal{E}}^{\mathrm{vect}}(\mathbb{C}P^2) of the category DGvect(CP2)\mathit{DG}^{\mathrm{vect}}(\mathbb{C}P^2) consisting of holomorphic vector bundles over the complex projective plane CP2\mathbb{C}P^2. As an application, we study the mirror description for global sections of the holomorphic tangent bundle over CP2\mathbb{C}P^2.
