Zeros of Partial Fractions 363 Zero - Free Regions of Linear Partial Fractions
when the a/s are complex constants. The case of real a/s has already been adequately treated by Gauss, Lucas, Jensen, and Bôcher in connection with their study of the derivative of a polynomial and the jacobian of two binary forms. In terms of $, their results may be stated as follows. (a) If all the ay's have the same sign, there are no zeros of $ outside of any convex polygon enclosing the po...
متن کاملZero-free Regions for Dirichlet Series
In this paper, we are interested in explicit zero-free discs for some Dirichlet series and we also study a general Beurling-Nyman criterion for Lfunctions. Our results generalize and improve previous results obtained by N. Nikolski and by A. de Roton. As a concrete application, we get, for example, a Beurling-Nyman type criterion for the Siegel zero problem.
متن کاملZero-free Regions of Radar Ambiguity Functions and Moments
In this article, we give an estimate of the zero-free region around the origin of the ambiguity function of a signal u in terms of the moments of u. This is done by proving an uncertainty relation between the first zero of the Fourier transform of a non-negative function and the moments of the function. As a corollary, we also give an estimate of how much a function needs to be translated to ob...
متن کامل$C_4$-free zero-divisor graphs
In this paper we give a characterization for all commutative rings with $1$ whose zero-divisor graphs are $C_4$-free.
متن کاملCOMPUTATION OF q-PARTIAL FRACTIONS
We study a special partial fraction technique which is designed for rational functions with poles on the unit circle, known as q-fractions. Even though the theory of q-partial fractions has already been applied to the Rademacher Conjecture, no systematic computational development appeared. In this paper we present two algorithms for the computation of q-partial fractions and highlight certain p...
