Abstract
Dromions are exact, localized solutions of (2+1) dimensional evolution equations and decay exponentially in all directions. 'Solitoffs' of t he Davey-Stewartson equations constitute an intermediate state between dromions end plane solitons, since they decay exponentially in all di rections except a preferred one. Here solitoffs are rederived by the H irota bilinear operator and extended to a variety of nonlinear evoluti on equations.
