 It is demonstrated that planar solitary waves of the
longitudinal compression can propagate in a graphene
sheet with supersonic velocities from a narrow range. In
an infinite sheet, such a solitary wave does not change its
shape, and interaction between two solitary waves is elastic
with no energy loss for radiation. However, in a graphene
nanoribbon the solitary waves are affected by the nanoribbon
edges which stipulate the phonon emission. As a result, the
soliton lifetime becomes finite, and it is roughly equal to the
double width of the nanoribbon.
