In this paper we show first of all that for solutions of the strict KP hierarchy it is sufficient to work in a standard setting. Further we discuss a minimal realization of the hierarchy and present the scaling invariance of the Lax equations of the hierarchy.
Keywords: pseudo differential operators, strict KP hierarchy, scaling transformations, minimal realization.
Mots-clés : Lax equations
