DESCRIPTION:We study the dynamical stability of five-dimensional Myers-Per
 ry black holes with equal angular momenta which  have an enlarged symmetry
 \, U(2). Using this symmetry\, we derive master\nequations for a part of m
 etric perturbations\nwhich are relevant to the stability. Based on the mas
 ter equations\,\nwe prove the stability of Myers-Perry black holes under t
 hese perturbations.\nOur result gives strong evidence for the stability of
 \nMyers-Perry black holes with equal angular momenta.\nWe also apply the f
 ormalism to the Kerr-AdS$_5\\times S^5$ spacetime\nwith equal angular mome
 nta.\nIn this spacetime\, we found the two types of classical instability\
 ,\nsuperradiant and Gregory-Laflamme.\nWe discuss the gauge dual of these 
 instabilities.\n
