In this paper, we apply the idea of T-duality to projective spaces. From a connection of a line bundle on \$\textbackslashmathbb Pˆn\$, a Lagrangian in the mirror Landau-Ginzburg model is constructed. Under this correspondence, the full strong exceptional collection \$\textbackslashmathcal O\_\textbackslashmathbb Pˆn(-n-1),...,\textbackslashmathcal O\_\textbackslashmathbb Pˆn(-1)\$ is mapped to standard Lagrangians in the sense of Nadler-Zaslow. Passing to constructible sheaves, we explicitly compute the quiver structure of these Lagrangians, and find that they match the quiver structure of this exceptional collection of \$\textbackslashmathbb Pˆn\$. In this way, T-duality provides quasi-equivalence of the Fukaya category containing these Lagrangians and the category of coherent sheaves on \$\textbackslashmathbb Pˆn\$, which is a kind of homological mirror symmetry.
