In this paper, we apply the idea of T-duality to projective spaces. From a connection on a line bundle on P, a Lagrangian in the mirror Landau–Ginzburg model is constructed. Under this correspondence, the full strong exceptional collection OPn(−n − 1), . . . , OPn(−1) is mapped to standard Lagrangians in the sense of [23]. 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 P. In this way, T-duality provides quasi-equivalence of the Fukaya category generated by these Lagrangians and the category of coherent sheaves on P, which is a kind of homological mirror symmetry.
