Bounds for Hilbert coefficients

, 2007
We compute the Hilbert coefficients of a graded module with pure resolution and discuss lower and upper bounds for these coefficients for arbitrary graded modules.

Coefficient bounds for the inverse of a function with derivative in 𝒫 [PDF]

Proceedings of the American Mathematical Society, 1983
Coefficient bounds for functions with a positive real part are used in a rather novel way to find sharp bounds for the first six coefficients of a function which is inverse to a regular normalized univalent function whose derivative has a positive real part in the unit disk.

On the Coefficient Problem of Meromorphic Harmonic Mappings

Demonstratio Mathematica, 2014
In this paper, we shall study estimates for the coefficients an, n = 1,2 of a class of univalent harmonic mappings defined on the exterior of the unit disk Ũ = { z : |z| > 1 }, which keep infinity fixed.

Coefficient Bounds for Certain Classes of Meromorphic Functions

Journal of Inequalities and Applications, 2008
Sharp bounds for are derived for certain classes and of meromorphic functions defined on the punctured open unit disk for which and , respectively, lie in a region starlike with respect to 1 and symmetric with respect to the real axis.

Polynomial Stabilization with Bounds on the Controller Coefficients∗∗##

IFAC-PapersOnLine, 2015
Let b/a be a strictly proper reduced rational transfer function, with a monic. Consider the problem of designing a controller y/x, with deg(y) < deg(x) < deg(a) – 1 and x monic, subject to lower and upper bounds on the coefficients of y and x, so that the poles of the closed loop transfer function, that is the roots (zeros) of ax + by, are, if possible,

Coefficient Bounds for q-Noshiro Starlike Functions in Conic Region

Journal of Function Spaces
We present and examine a new family of analytic functions that can be described by a q-Ruscheweyh differential operator. We discuss several novel results, including coefficient inequalities and other noteworthy properties such as partial sums and radii ...

Ozaki-Type Bi-Close-to-Convex and Bi-Concave Functions Involving a Modified Caputo’s Fractional Operator Linked with a Three-Leaf Function

Fractal and Fractional
The focus of the present work is on the establishment and investigation of the coefficient estimates of two new subclasses of bi-close-to-convex functions and bi-concave functions; these are of an Ozaki type and involve a modified Caputo’s fractional ...
