pq , -Order of Solutions of Linear Differential Equations in the Unit Disc

In this paper, we investigate the ( ) pq , -order of solution of second-order linear differential equa- tion ( ) ( ) ( ) '' ' f A zf A z f F z 10 + + = , where ( ) Az 0 , ( ) Az 1 and ( ) Fz are analytic functions in the unit disc. We obtain several theorems about the growth and oscillation of solutions of differential equations.
