On some regular and singular problems of Birkhoff interpolation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
Here we investigate the pure (0,1,…,r−2,r)-interpolation problem on the zeros of (1−x2)Pn(α)(x)=(1−x2)Pn(α,α)(x), α>−1, where Pn(α,α)(x) is the Jacobi polynomial of degree n with β=α.

Complex oscillations of non-definite Sturm-Liouville problems, II

open access: yesElectronic Journal of Qualitative Theory of Differential Equations
We correct and update a result of R. G. D. Richardson [Amer. J. Math. 40(1918), 283–316] dealing with the separation of zeros of the real and imaginary parts of non-real eigenfunctions of non-definite Sturm–Liouville eigenvalue problems.

Questions around the nontrivial zeros of the Riemann zeta-function. Computations and classifications

open access: yesMathematical Modelling and Analysis, 2011
We study the sequence of nontrivial zeros of the Riemann zeta-function with respect to sequences of zeros of other related functions, namely, the Hurwitz zeta-function and the derivative of Riemann's zeta-function.

Zero-over-Zero Theorem

open access: yes, 2022
In this paper, we provide definitions and proof of the Zero-over-Zero Theorem. This theorem would be some help for the 0/0 problem.

Some inequalities for rational function with prescribed poles and restricted zeros

open access: yesDemonstratio Mathematica
In this article, we first prove some auxiliary results in the form of lemmas using an improved Schwarz lemma at the boundary recently proved by Mercer. Furthermore, we establish some new inequalities for rational functions on the unit disk in the complex

La hipòtesi de Riemann: El gran repte pendent

open access: yesMètode Science Studies Journal: Annual Review, 2018
La hipòtesi de Riemann és una afirmació, no demostrada, que fa referència als zeros de la funció zeta de Riemann. Bernhard Riemann calculà els sis primers zeros no trivials d’aquesta funció i observà que tots estaven sobre una mateixa recta.

On Polynomials Associated with Finite Topologies

open access: yesAxioms
Let τ be a topology on the finite set Xn. We consider the open-set polynomial associated with the topology τ. Its coefficients are the cardinalities of sets Uj=Uj(τ) of open sets of size j=0,…,n.

Improving the Asymptotic Properties of Discrete System Zeros in Fractional-Order Hold Case

open access: yesJournal of Applied Mathematics, 2013
Remarkable improvements in the asymptotic properties of discrete system zeros may be achieved by properly adjusted fractional-order hold (FROH) circuit.
