In this paper, we study the complex oscillation of solutions and their derivatives of the differential equation f 00 + A (z) f 0 + B (z) f = F (z) , where A (z) , B (z) (6≡ 0) and F (z) (6≡ 0) are meromorphic functions ...

In this paper we give an estimate, from below and from above, of the mean value of the function f : [a, b] → R such that f is continuous on [a, b] and twice differentiable on (a, b).

In this paper, we will show some new inequalities for convex functions, and we will also make a connection between them and Chebyshev's inequality, which implies the existence of new class of functions satisfying Chebyshev's ...

In this paper, we give a complete answer to Problem 1 and a partial answer to Problem 2 posed by F. Qi in [2] and we propose an open problem. Acknowledgements: The authors would like to thank the referees for their helpful ...

In this paper, we investigate the growth and oscillation of higherorder differential polynomial with meromorphic coefficients in the unit disc∆ ={z:|z|<1}generated by solutions of the linear differential ...

 roughout this paper, we assume that the reader is familiar with the fundamental results and the standard notations of the Nevanlinna value distribution theory (see [1–4]). In addition, we will use 𝜆𝜆𝐴𝑓𝑓𝐴 and ...
