Abstract
We discuss the zero-dispersion limit for the Benjamin-Onoequation on the torus given a bell-shaped initial data. We provethat the solutions admit a weak limit as the dispersion parametertends to zero which is explicit and constructed from the Burgersequation. The approach relies on the complete integrability forthe Benjamin-Ono equation from Gerard, Kappeler and Topalovand also on the spectral study of the Lax operator associated tothe initial data in the zero-dispersion limit.
