Using this symmetry, we derive master equations for a part of metric perturbations which are relevant to the stability. Based on the master equations, we prove the stability of Myers-Perry black holes under these perturbations. Our result gives a strong evidence for the stability of Myers-Perry black holes with equal angular momenta.22 pages, 3 figuresHigh Energy Physics - TheoryGeneral Relativity and Quantum Cosmologytext
