Let Q be the class of functions of the form f z s y1rz q c q c z q ะธะธะธ 0 1

< < which are meromorphic in the unit disk z -1 and satisfy there the condition ลฝ . ร„ 4 ร„ ลฝ .4 f z / 0 and แ‘ฃ z ะธ แ‘ฃ f z ) 0 for nonreal z. We determine the radius of starlikeness of order โฃ, yฯฑ -โฃ -1, and the maximal domain of univalence of the class Q.

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.
