Abstract
When both gravity and surface tension effects are present, surface solitary water waves are known to exist in both two and threedimensional infinitely deep fluids. We describe here solutions bridging these two cases: travelling waves which are localized in the propagation direction and periodic in the transverse direction. These transversally periodic gravitycapillary solitary waves are found to be of either elevation or depression type, tend to plane waves below a critical transverse period and tend to solitary lumps as the transverse period tends to infinity. The waves are found numerically in a Hamiltonian system for water waves simplified by a cubic truncation of the DirichlettoNeumann operator. This approximation has been proved to be very accurate for both two and threedimensional computations of fully localized gravitycapillary solitary waves. The stability properties of these waves are then investigated via the time evolution of perturbed wave profiles.
