Evolutionary forms, as well as exterior forms, are skew-symmetric differential forms. But in contrast to the exterior forms, the basis of evolutionary forms is deforming manifolds (manifolds with unclosed metric forms). Such forms possess a peculiarity, namely, the closed inexact exterior forms are obtained from that. The closure conditions of inexact exterior form (vanishing the differentials ...

In the present paper we construct a new intuitionistic fuzzy implication, giving form to Goguen’s implication. Some of its basic properties are studied and illustrated with examples. Geometrical interpretations different forms implication given. Other discussed.
