Abstract
With the advent of the recent measurements in neutrino physics, we investigate the role of high-energy neutrino flux ratios at neutrino telescopes for the possibility of determining the leptonic CP-violating phase \delta and the underlying pattern of the leptonic mixing matrix. We find that the flux ratios show a dependence of O(10 %) on the CP-violating phase, and for optimistic uncertainties on the flux ratios less than 10 %, they can be used to distinguish between CP-conserving and CP-violating values of the phase at 2\sigma in a non-vanishing interval around the maximal value |\delta|=\pi/2.
