A Study of the Behavior of Ultra-High Energy Neutrinos
  Neutrino Oscillations in the presence of strong gravitational fields are studied specifically for Majorana neutrinos. We look at ultra high energy neutrinos $(\sim 1$ PeV) emanating from Active Galactic Nuclei (AGN). Fluxes of different flavor neutrinos are estimated and probabilities for different neutrino transitions calculated.
