Bounds on the coefficients of tension and flow polynomials [PDF]

open access: yesJournal of Algebraic Combinatorics, 2010
The goal of this article is to obtain bounds on the coefficients of modular and integral flow and tension polynomials of graphs. To this end we make use of the fact that these polynomials can be realized as Ehrhart polynomials of inside-out polytopes.

Faber Polynomial Coefficient Estimates for Subclass of Analytic Bi-Bazilevic Functions Defined by Differential Operator

open access: yesمجلة بغداد للعلوم, 2019
In this work,  an explicit formula for a class of Bi-Bazilevic univalent functions involving differential operator is given, as well as the determination of upper bounds for the general Taylor-Maclaurin coefficient of a functions belong to this class ...

Yamaguchi -Noshiro Type Bi-Univalent Functions Associated with Sălăgean-Erdély–Kober Operator

open access: yesMathematics, 2022
We defined two new subclasses of analytic bi-univalent function class Σ, in the open unit disk related with the Sălăgean–Erdély–Kober operator. The bounds on initial coefficients |a2|,|a3| and |a4| for the functions in these new subclasses of Σ are ...

Some Bounds for the Fragmentation Coefficient of Random Graphs

open access: yesAxioms
Graph fragmentation aims to find the smallest vertex subset whose removal breaks a graph into components of bounded size. While this problem has applications in network dismantling and combinatorics, theoretical bounds on optimal solutions remain limited.

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 ...

On the Coefficients of Functions with Bounded Boundary Rotation [PDF]

open access: yesProceedings of the American Mathematical Society, 1972
Let V7k be the class of normalised functions of bounded boundary rotation. For fe Vk define M(r,f) = max If(z)I, IzI=r and let L(r,f) denote the length of f(Izl =r). Then if f(z)=z+ ,'?n=2anz, it is shown that (i) 2M(r,f)

Certain Subclasses of Bi-Starlike Function of Complex Order Defined by Erdély–Kober-Type Integral Operator

open access: yesAxioms, 2022
In the present paper, we introduce new subclasses of bi-starlike and bi-convex functions of complex order associated with Erdély–Kober-type integral operator in the open unit disc and find the estimates of initial coefficients in these classes. Moreover,
