title: Pulse dynamics in a chain of granules with friction.
abstract: We study the dynamics of a pulse in a chain of granules with friction. We present theories for chains of cylindrical granules (Hertz potential with exponent n=2) and of granules with other geometries (n>2). Our results are supported via numerical simulations for cylindrical and for spherical granules (n=5/2).
