Argument estimates of certain meromorphic functions associated with the generalized Bessel function

Argument estimates of certain meromorphic functions associated with the generalized Bessel function

The purpose of the present paper is to derive some inclusion properties and argument estimates of certain classes of meromorphic functions in the punctured unit disc, which are defined by means of Bessel function. Furthermore, the integral preserving properties in a sector are investigated.
