Jaroš, J.; Kusano, T. A Picone type identity for second-order half-linear differential equations. (English) Zbl 0926.34023 Acta Math. Univ. Comen., New Ser. 68, No. 1, 137-151 (1999). Summary: A Picone-type identity for half-linear differential equations of second order is derived and a Sturmian theory for both forced and unforced half-linear and quasilinear equations based on this identity is developed.
