Limit curves for zeros of sections of exponential integrals [PDF]

, 2014
We are interested in studying the asymptotic behavior of the zeros of partial sums of power series for a family of entire functions defined by exponential integrals.

A new method for solving nonlinear systems of equations that is based on functional iterations

Open Physics, 2018
Regarding solving nonlinear equations systems, there is a main problem that is the number and complexity of the linear algebra operations, and the functional evaluations of the applied algorithm. In this paper, an alternative solution will be proposed by

Zeros of Convex Combinations of Elementary Families of Harmonic Functions

Mathematics, 2023
Brilleslyper et al. investigated how the number of zeros of a one-parameter family of harmonic trinomials varies with a real parameter. Brooks and Lee obtained a similar theorem for an analogous family of harmonic trinomials with poles. In this paper, we

Lee-Yang-Fisher zeros for DHL and 2D rational dynamics, II. Global Pluripotential Interpretation [PDF]

, 2019
In a classical work of the 1950's, Lee and Yang proved that for fixed nonnegative temperature, the zeros of the partition functions of a ferromagnetic Ising model always lie on the unit circle in the complex magnetic field.

REFINEMENT OF SOME BERNSTEIN TYPE INEQUALITIES FOR RATIONAL FUNCTIONS

Проблемы анализа, 2022
In this paper, we establish some Bernstein-type inequalities for rational functions with prescribed poles. These results refine prior inequalities on rational functions and strengthen many well-known polynomial inequalities.

Weak Boson Production Amplitude Zeros; Equalities of the Helicity Amplitudes [PDF]

, 2001
We investigate the radiation amplitude zeros exhibited by many Standard Model amplitudes for triple weak gauge boson production processes. We show that $WZ\gamma$ production amplitudes have especially rich structure in terms of zeros, these amplitudes ...

Radiation zeros and scalar particles beyond the standard model [PDF]

, 1998
Standard radiation zeros arise from the factorization properties of tree-level amplitudes involving a massless photon and can occur when all charged particles in the initial and final state have the same sign.

REFINEMENT OF ERD ¨OS-LAX INEQUALITY FOR N-OPERATOR

Проблемы анализа
Let 𝒫_𝑛 be the space of all polynomials of degree less than or equal to 𝑛. In this paper, we establish a refinement of Erd¨os-Lax inequality in which the classical derivative (as an operator on 𝒫_𝑛) is replaced by a 𝐵𝑛 operator.

Algorithms of predictor-corrector type with convergence and stability analysis for solving nonlinear systems

AIMS Mathematics
Many researchers have proposed iterative algorithms for nonlinear equations and systems of nonlinear equations; similarly, in this paper, we developed two two-step algorithms of the predictor-corrector type.

Stability of Zeros for Sampled-Data Models with Triangle Sample and Hold Implemented by Zero-Order Hold

Machines, 2022
This paper deals with the stability characteristics of zeros for sampled-data models with a class of triangle sample and hold realized by a traditional zero-order hold.
