โฆ Synopsis
In this paper, we study the normality of a family of meromorphic functions concerning shared values and prove the following theorem: Let F F be a family of meromorphic functions in a domain D, let k G 2 be a positive integer, and let a, b, c be complex numbers such that a / b. If, for each f g F F, f and f ลฝ k . share a and ลฝ . b in D, and the zeros of f z y c are of multiplicity G k q 1, then F F is normal in D.

In this paper, by studying the counting functions of the common 1-points of meromorphic functions, a more precise relation between the characteristics of meromorphic functions that share three values CM has been obtained. As applications of this, many known results can be improved.
Making use of a linear operator, which is defined here by means of the Hadamard product (or convolution), the authors introduce (and investigate the various properties and characteristics of) two novel families of meromorphically multivalent functions. They also extend the familiar concept of neighb
