AB - The AMANDA-II neutrino telescope detects upward-going atmospheric muon neutrinos penetratingthe Earth from the Northern Hemisphere via the Cherenkov light of neutrino-induced muons,allowing the reconstruction of the original neutrino direction. Due to the high energy threshold of about 50 GeV, the declination spectrum is minimally affected by standard neutrino oscillations; however, alternative oscillation models predicting subdominant effects can be tested and constrained. Of particular interest are models that allow one to test Lorentz invariance and the equivalence principle. Using the AMANDA-II data from the years 2000 to 2003, a sample of 3401 candidate neutrino-induced events was selected. No indication for alternative oscillation effects was found. For maximal mixing angles, an upper limit is set on both the Lorentz violation parameter δc/c and the equivalence principle violation parameter 2 - φ - δγ of 5.3 × 10−27 at the 90
