Fourth Hankel and Toeplitz determinant estimates for certain analytic functions associated with Four Leaf function

open access: yesExtracta Mathematicae
The objective of this paper is to establish initial coefficient inequalities, Upper bounds to the Hankel and Toeplitz determinants for certain normalized univalent functions defined on the open unit disk D in the complex plane related to the analytic ...

Inverse and Logarithmic Coefficient Bounds of Concave Univalent Functions

open access: yesAxioms
The concept of coefficient estimates on univalent functions is one of the interesting aspects explored recently by many researchers. Motivated by this direction, in this present work, we obtain the upper bounds of initial inverse coefficients and ...

Bidiagonal Factorizations of Filbert and Lilbert Matrices

open access: yesAxioms
Extensions of Filbert and Lilbert matrices are addressed in this work. They are reciprocal Hankel matrices based on Fibonacci and Lucas numbers, respectively, and both are related to Hilbert matrices.
