Sharp Bounds for Higher-Order Schippers Functionals Associated with Lune and Bean Domains
Firdoshi Parveen, Pradip Das
We obtain sharp bounds for the third- and fourth-order Schippers functionals, and , for subclasses of univalent functions associated with non-classical g…
Sharp Hankel and Hermitian--Toeplitz Determinants Involving Logarithmic and Inverse Logarithmic Coefficients for the class \(\mathcal{S}_{car}^*\)
Nabadwip Sarkar, Pradip Das
This paper focuses on coefficient problems for the class of starlike functions related to a cardioid region. We derive sharp bounds for the Hankel determinants of logarithmic coeff…
Second Hankel Determinant for -Spirallike Convex Mappings in Complex Banach Spaces
Molla Basir Ahamed, Nabadwip Sarkar, Pradip Das
We establish the bound for the second-order Hankel determinant associated with the class of normalized -spirallike…
Bohr-type inequalities with Fréchet derivative and Area terms in Complex Banach spaces
Nabadwip Sarkar, Pradip Das
We establish new Bohr-type inequalities for holomorphic mappings from the unit ball of a complex Banach space into the closed unit disk. Using Fréchet derivatives, Schwarz mapping…
Higher-Order Schippers-Schwarzian Derivatives for Non-Circular Starlike Functions
Pradip Das, PaweÅ Zaprawa, Nabadwip Sarkar
The paper determines exact upper bounds for the third and fourth higher-order Schippers‑Schwarzian derivatives at the origin for several subclasses of univalent and starlike functi…
Coefficient Problems and Sharp Determinant Estimates for the Class
Pradip Das, Nabadwip Sarkar
The paper derives sharp bounds for logarithmic and inverse logarithmic coefficients, as well as second-order Hankel and Hermitian‑Toeplitz determinants, for a subclass of normalize…
