Third Hankel Determinant for a Subclass of Univalent Functions Associated with Lemniscate of Bernoulli

open access: yesFractal and Fractional, 2022
This paper deals with a new subclass of univalent function associated with the right half of the lemniscate of Bernoulli. We find the upper bound of the Hankel determinant H3(1) for this subclass by applying the Carlson–Shaffer operator to it.

Some Results Concerned with Hankel Determinant

open access: yesKragujevac Journal of Mathematics, 2023
Summary: In this paper, we discuss different versions of the boundary Schwarz lemma and Hankel determinant for \(\mathcal{K}\left( \alpha \right)\) class. Also, for the function \(f(z)=z+c_2z^2+c_3z^3+\cdots\) defined in the unit disc such that \(f\in \mathcal{K(\alpha)}\), we estimate a modulus of the angular derivative of \(f(z)\) function at the ...

Evaluation of a Special Hankel Determinant of Binomial Coefficients [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
This paper makes use of the recently introduced technique of $\gamma$-operators to evaluate the Hankel determinant with binomial coefficient entries $a_k = (3 k)! / (2k)! k!$. We actually evaluate the determinant of a class of polynomials $a_k(x)$ having

Bounds for the Second Hankel Determinant of a General Subclass of Bi-Univalent Functions [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences
The Hankel determinant, which plays a significant role in the theory of univalent functions, is investigated here in the context of bi-univalent analytic functions.

Selberg integrals and Hankel determinants [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
In our previous works "Pfaffian decomposition and a Pfaffian analogue of $q$-Catalan Hankel determinants'' (by M.Ishikawa, H. Tagawa and J. Zeng, J. Combin. Theory Ser. A, 120, 2013, 1263-1284) we have proposed several ways to evaluate certain Catalan-Hankel Pffafians and also formulated several conjectures.
