Bounds for the Second Hankel Determinant of Certain Univalent Functions
Lee See Keong, V. Ravichandran, Shamani Supramaniam
The estimates for the second Hankel determinant a_2a_4-a_3^2 of analytic function f(z)=z+a_2 z^2+a_3 z^3+...b for which either zf'(z)/f(z) or 1+zf"(z)/f'(z) is subordinate to certa…
Applications of differential subordination for functions with fixed second coefficient to geometric function theory
Lee See Keong, V. Ravichandran, Shamani Supramaniam
The theory of first-order differential subordination developed by Miller and Mocanu was recently extended to functions with fixed initial coefficient by R. M. Ali, S. Nagpal and V.…
Close-to-convexity and starlikeness of analytic functions
Lee See Keong, V. Ravichandran, Shamani Supramaniam
For functions defined on the open unit disk, the condition is sufficient for close-to-convexity of . By making use of this…
Initial Coefficients of Bi-univalent Functions
See Keong Lee, V. Ravichandran, Shamani Supramaniam
An analytic function defined on the open unit disk is bi-univalent if the function and its inverse are univalent in . Estimate…
