Singular values of one parameter family lambda(z/(e^z-1))^m

摘要

In this paper, the singular values of one parameter family of mero-morphic functions f (z) = ( zez..1 )m and f (0) = , m 2 Nnf0g, 2 Rnf0g, z 2 C are studied. It is shown that all the critical val-ues of f (z) lie in the left half plane outside the open disk centered atorigin and having radius j j. Further, it is describ
