Transmission irregular starlike and double starlike tree confirmation script

<p>This Python script provides a computer-assisted proof of the fact that the 11 experimentally obtained infinite families of starlike and double starlike trees truly consist of only transmission irregular graphs.</p ...

Starlike meromorphic functions

, 1972
In this paper we study meromorphic univalent functions which map the unit disk onto the exterior of a domain which is starlike with respect to some finite point different from the origin.

On a Subclass of Starlike Functions

Rocky Mountain Journal of Mathematics, 1994
Let \(A\) denote the class of functions \(f(z)= z+ \sum^ \infty_{k= 2} a_ k z^ k\) analytic in the unit disk \(D\), \(S\) and \(S^*\) denote the usual subclasses of univalent and starlike functions. For \(\beta< 1\) let \[ R(\beta)= \{ f\in A: \text{Re}(f'(z)+ zf''(z))> \beta,\;z\in D\}\text{ and } \beta_{S^*}= \inf\{\beta: R(\beta)\subset S^*\}. \] In

Coefficient Bounds and Stability for an Arctangent–Superexponential Convolution Class

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This paper presents a new convolution framework for normalized analytic functions in the open unit disk. The framework uses an arctangent and superexponential coefficient kernel, with each part serving a different purpose. The arctangent factor controls the early Taylor coefficients, while the cubic superexponential factor quickly reduces the higher ...

q‐Poisson and q‐Pascal Distribution Series for Analytic Function Classes

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In this paper, we study analytic function classes defined by the q‐derivative and convolution operators generated by discrete q‐distributions. We first consider coefficient conditions for the class determined by a q‐derivative inequality and its negative‐coefficient subclass. We then investigate the q‐Poisson and q‐Pascal distribution series and derive

On α-Pseudo Spiralike Functions Associated with Exponential Pareto Distribution (EPD) and Libera Integral Operator

Mathematics
The present study aims at investigating some characterizations of a new subclass Gα(μ,τ) and obtaining the bounds on the first two Taylor–Maclaurin coefficients for functions belonging to the newly introduced subclass.
