Lower bounds on the bounded coefficient complexity of bilinear maps [PDF]

open access: yesJournal of the ACM, 2003
We prove lower bounds of order n log n for both the problem of multiplying polynomials of degree n , and of dividing polynomials with remainder, in the model of bounded coefficient arithmetic circuits over the complex numbers. These lower bounds are optimal up to order

Initial Coefficient Bounds for Bi-Univalent Functions Related to Gregory Coefficients

open access: yesMathematics, 2023
In this article we introduce three new subclasses of the class of bi-univalent functions Σ, namely HGΣ, GMΣ(μ) and GΣ(λ), by using the subordinations with the functions whose coefficients are Gregory numbers. First, we evidence that these classes are not

Bounds for Hilbert Coefficients [PDF]

open access: yesTaiwanese Journal of Mathematics, 2021
Let \((R,\mathfrak{m})\) be a noetherian local ring of Krull dimension \(d\), and \(\mathfrak{a}\) an \(\mathfrak{m}\)-primary ideal of \(R\), i.e. \(\sqrt{\mathfrak{a}}=\mathfrak{m}\). The Hilbert-Samuel function \(H_{\mathfrak{a}}(-):\mathbb{Z}\rightarrow \mathbb{N}_{\geq 0}\) of \(R\) with respect to \(\mathfrak{a}\) is given by \(H_{\mathfrak{a}}(n)

Applications of Borel distribution series on holomorphic and bi-univalent functions [PDF]

open access: yesMathematica Moravica, 2021
In present manuscript, we introduce and study two families BS(l, d; a) and B * S (l, d; b) of holomorphic and bi-univalent functions which involve the Borel distribution series. We establish upper bounds for the initial Taylor-Maclaurin coefficients |a2|

Logarithmic Coefficient Bounds and Coefficient Conjectures for Classes Associated with Convex Functions

open access: yesJournal of Function Spaces, 2021
It is well-known that the logarithmic coefficients play an important role in the development of the theory of univalent functions. If S denotes the class of functions fz=z+∑n=2∞anzn analytic and univalent in the open unit disk U, then the logarithmic ...

Bounding the first Hilbert coefficient [PDF]

open access: yesProceedings of the American Mathematical Society, 2011
This paper gives new bounds on the first Hilbert coefficient of an ideal of finite colength in a Cohen-Macaulay local ring. The bound given is quadratic in the multiplicity of the ideal. We compare our bound to previously known bounds and give examples to show that at least in some cases it is sharp.

A method for estimating width bands of variables in economics under uncertainty conditions

open access: yesMethodsX, 2021
This study develops a method to estimate the width bands of variables in economics by fuzzy logic. One of its important features is flexibility in the conditions of economic uncertainty, which can be used to model the uncertainty of external and internal

Frame approximation with bounded coefficients [PDF]

open access: yesAdvances in Computational Mathematics, 2021
Due to their flexibility, frames of Hilbert spaces are attractive alternatives to bases in approximation schemes for problems where identifying a basis is not straightforward or even feasible. Computing a best approximation using frames, however, can be challenging since it requires solving an ill-conditioned linear system.
