Let f be a nonconstant meromorphic function defined in the whole complex plane . It is assumed that the reader is familiar with the notations of the Nevanlinna theory such as T r, f , m r, f ,N r, fâ€¦ (More)

Many Drosophila species exhibit genetic variation in traits affecting mate choice (Scott & Richmond, 1988; MarÃµÃ‚n, 1994; Aspi & Hoikkala, 1995). This variation forms the basis for sexual selectionâ€¦ (More)

In this paper, we study the problem of meromorphic functions sharing a small function with its derivative and prove one theorem. The theorem improves the results of Lahiri-Sarkar [J.Ineq.Pureâ€¦ (More)

The main purpose of this paper is to introduce and investigate a certain subclass of meromorphic close-to-convex functions. Such results as coefficient inequalities, convolution property, inclusionâ€¦ (More)
