Abstract
Estimates of physically relevant quantities (cross sections, multiplicities, correlations) in eikonal models of high-energy field theories lead to a class of semiclassical solutions to non-linear Euler equations. The requirement of unitarity restricts these possible solutions to a unique function of energy and impact parameter.
