✦ Synopsis

We construct a meromorphic matrix function with given spectral data in the form of null and pole functions, coupling matrix, and left annihilator at every point in the domain of definition of the function. Based on these results, descriptions are given of minimal divisibility of meromorphic matrix functions in terms of restric-Ž . tions appropriately understood of their spectral data.

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.
