Properties of a Class of Analytic Functions Influenced by Multiplicative Calculus
Fractal and FractionalMotivated by the notion of multiplicative calculus, more precisely multiplicative derivatives, we used the concept of subordination to create a new class of starlike functions.

Laplacian spectral determination of path-friendship graphs
AKCE International Journal of Graphs and Combinatorics, 2021 A graph G is said to be determined by the spectrum of its Laplacian matrix (DLS) if every graph with the same spectrum is isomorphic to G. In some recent papers it is proved that the friendship graphs and starlike trees are DLS. If a friendship graph and

Journal of Function Spaces, Volume 2026, Issue 1, 2026.In this paper, we study several important coefficient problems for the class Sp∗ of Sakaguchi‐type starlike functions subordinated to a petal‐shaped domain. We obtain a collection of sharp bounds that extend and refine known results in geometric function theory.

A new subclass of the meromorphic harmonic γ-starlike functions
, 2011 Recently Bostanci and Ozturk defined a new operator M-n for meromorphic harmonic functions. They introduced new classes of meromorphic harmonic starlike functions in (U) over tilde = (z : vertical bar z vertical bar > 1) using operator M-n. In this work,

Tarantula graphs are determined by their Laplacian spectrum
Electronic Journal of Graph Theory and Applications, 2021 A graph G is said to be determined by its Laplacian spectrum (DLS) if every graph with the same Laplacian spectrum is isomorphic to G. A graph which is a collection of hexagons (lengths of these cycles can be different) all sharing precisely one vertex ...

Hankel determinant for functions starlike and convex with respect to symmetric points [PDF]
, 2006 Sakaguchi (1959) introduced the class of functions S*s , starlike with respect to symmetric points. In 1977, Das and Singh introduced similar class of functions Cs , convex with respect to symmetric points.

A Two‐Parameter Subclass of q‐Starlike Functions Associated With 1−sinz/cosz
Journal of Function Spaces, Volume 2026, Issue 1, 2026.Using the real parameters λ and τ with −1 ≤ τ < λ < 1, a generalized q−extension ψqz;λ,τ of the function ψz=1−sinz/cosz, in O´=z∈ℂ:z<1, is defined. The function ψqz;λ,τ is then used as a subordination function to construct a novel subclass; STq∗λ,τ of q−starlike functions.

Null, recursively starlike-equivalent decompositions shrink [PDF]
, 2019 A subset $E$ of a metric space $X$ is said to be starlike-equivalent if it has a neighbourhood which is mapped homeomorphically into $\mathbb{R}^n$ for some $n$, sending $E$ to a starlike set.

Starlike Functions With Respect to a Boundary Point Connected With Bounded Radius Rotation
Journal of Function Spaces, Volume 2026, Issue 1, 2026.In the current article, we introduce a new subclass of univalent function Gμ with bounded radius rotation. For this new class, the authors establish many interesting relations between these classes and existing classes. Furthermore, authors try to find coefficient estimations for this new subclass.

Certain Geometric Investigations of Three Normalized Bessel-Type Functions of a Complex Variable
MathematicsWe recall the normalized forms for the three Bessel-type functions; these functions are the Bessel function, Lommel function, and Struve function of the first kind. By using convolution, we define normalized forms.
