DESCRIPTION:We present two general stability/instability criteria for nonl
 inear waves in Hamiltonian or reversible systems. Both criteria rely upon 
 spectral properties of the linear operators found by linearizing the syste
 m at a given wave. We apply these results to some model equations arising 
 in water-wave problems. The focus is on the question of transverse&nbsp\; 
 stability/instability of periodic traveling waves. <br><br><br>
