Contact elements, contact correspondences, and contact invariants
Copyright policy )Contact elements, contact correspondences, and contact invariants
Il lavoro da una teoria moderna delle trasformazioni di contatto e dei loro invarianti differenziali. I teoremi principali di Lie e Backlund sono dimostrati e illustrati; si danno esempi che contraddicono teoremi di Engel e Liebmann. Si segnalano campi di ricerche nei quali la teoria degli invarianti di Lie si mostra superiore al metodo del triedro mobile.
