Applications of the Jack's lemma for the meromorphic functions
(Springernature, 2021)
In this paper, we give some results on zf'(z)/f(z) for the certain classes of f(z) meromorphic functions. For the function f(z) = 1/z + c(0) + c(1)z + c(2)z(2)+ ... defined in the punctured disc U = {z : 0
Estimates Concerned with Hankel Determinant for M (?) Class
(Univ Nis, Fac Sci Math, 2022)
In this paper, we give an upper bound of Hankel determinant of (H2(1)) for the classes of M (alpha), alpha is an element of C. Also, for M (alpha), we obtain a sharp estimate for the classical Fekete-Szego center dot ...
