A Geometric Construction of Laguerre–Forsyth’s Canonical Forms of Linear Ordinary Differential Equations
Y. Se-ashi (B) If both ( t, {ea}) and ( t', { e~}) satisfy the condition (L.F), then there exists T = ( ~ ! ) E SL(2, IR) and C = (ca,a) E GL(r, IR) such that , at+ b t = -ct +d' r e~ = (ct+ dr-1 …
