SOME PROPERTIES OF COMBINATION OF SOLUTIONS TO SECOND-ORDER LINEAR DIFFERENTIAL EQUATIONS WITH ANALYTIC COEFFICIENTS OF [P; Q]-ORDER IN THE UNIT DISC

Abstract

In this paper, we consider some properties on the growth and oscillation of combination of solutions of the linear di erential equation f00 + A(z) f0 + B (z) f = 0; with analytic coe cients A(z) and B (z) with [p; q]-order in the unit disc = fz 2 C : jzj < 1g.
