Gamma conjecture I and the underlying Conjecture Ofor Fano manifolds were proposed by Galkin, Golyshev and Iritani recently. We show that both conjectures hold for all two-dimensional Fano manifolds. We prove Conjecture Oby deriving a generalized Perron-Frobenius theorem on eigenvalues of real matrices and a vanishing result of certain Gromov-Witten invariants for del Pezzo surfaces. We prove Gamma conjecture I by applying mirror techniques proposed by Galkin-Iritani together with the study of Gamma conjec-ture I for weighted projective spaces. We also provide applications of our generalized Perron-Frobenius theorem on Conjecture O for two Fano manifolds of higher dimensions.
