Can someone give me a good reference on paradifferential operators? I have seen bits and pieces about them in monographs but nowhere a formal definition or motivation for its uses. Is this an extension of pseudodifferential operators to nonlinear PDE? How on earth one would do that is not clear to me. Compsonheir (talk) 11:15, 17 June 2009 (UTC)Reply
