Abstract
In a recent publication we proposed an extension of Hirota's bilinear formalism to arbitrary multilinearities. The trilinear (and higher) operators were constructed from the requirement of gauge invariance for the nonlinear equation. Here we concentrate on the trilinear case, and use singularity analysis in order to single out equations that are likely to be integrable. New PDE's are thus obtained, along with others already well-known for their integrability and for which we obtain here the trilinear expression. To appear in the proceedings of NEEDS'94 (11-18 September, Los Alamos)
