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.…
Construction of subclasses of univalent harmonic mappings
Sumit Nagpal, V. Ravichandran
Complex-valued harmonic functions that are univalent and sense-preserving in the open unit disk are widely studied. A new methodology is employed to construct subclasses of univale…
Second-order differential subordinations for analytic functions with fixed initial coefficient
Rosihan M. Ali, Sumit Nagpal, V. Ravichandran
Functions with fixed initial coefficient have been widely studied. A new methodology is proposed in this paper by making appropriate modifications and improvements to the theory of…
Applications of Theory of Differential Subordination for Functions with Fixed Initial Coefficient to Univalent Functions
Sumit Nagpal, V. Ravichandran
By using the theory of first-order differential subordination for functions with fixed initial coefficient, several well-known results for subclasses of univalent functions are imp…
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…
On the radius constants for classes of analytic functions
Rosihan M. Ali, Naveen Jain, V. Ravichandran
Radius constants for several classes of analytic functions on the unit disk are obtained. These include the radius of starlikeness of a positive order, radius of parabolic starlike…
