Growth and oscillation theories of differential polynomials


Benharrat Belaïdi, Abdallah El Farissi




In this paper we investigate the complex oscillation and the growth of some differential polynomials generated by the solutions of the differential equation \[ f''+A_1(z)f'+A_0(z)f=F, \] where $A_1(z),A_0(z)(\not\equiv0)$, $F$ are meromorphic functions of finite order.
