New exact travelling solutions of the generalized Hirota equation
Partial Differential Equations in Applied Mathematics, 2021 In this paper, we solve the generalized Hirota equation with an external potential by means of the new Jacobi elliptic function rational expansion method and the exponential rational function method.

Rational Transfer Function Approximations to Transport Delay [PDF]
Modeling, Identification and Control, 1990 A method is presented for determining a rational transfer function approximation to transport delay which has the property that the error in the frequency response phase shift is zero at certain frequencies.

Extended Simulation Function via Rational Expressions
Mathematics, 2020 In this paper, we introduce some common fixed point theorems for two distinct self-mappings in the setting of metric spaces by using the notion of a simulation function introduced in 2015.

Introduction to Rational Functions [PDF]
Formalized Mathematics, 2012 Summary In this article we formalize rational functions as pairs of polynomials and define some basic notions including the degree and evaluation of rational functions [8]. The main goal of the article is to provide properties of rational functions necessary to prove a theorem on the stability of ...

Quadratic Poisson algebras on k[x, y, z]and their automorphisms
Қарағанды университетінің хабаршысы. Математика сериясы, 2016 One of the important directions in modern mathematics is applications of Poisson structures and to various problems of mathematics and theoretical mechanics. These problems arise in dynamics of a rigid body, the celestial mechanics, the theory of curls,

Multipartite Rational Functions
Documenta Mathematica, 2020 Consider a tensor product of free algebras over a field \Bbbk , the so-called multipartite free algebra \mathcal{A}=\Bbbk<X^{(1)}> \otimes\cdots\otimes\Bbbk<X^{(G)}>

Rational function decomposition [PDF]
Proceedings of the 1991 international symposium on Symbolic and algebraic computation, 1991 This paper presents a polynomial time algorithm for determining whether a given univariate rational function over an arbitrary field is the composition of two rational functions over that field, and finds them if so.

Rational Hypergeometric Functions [PDF]
Compositio Mathematica, 2001 Multivariate hypergeometric functions associated with toric varieties were introduced by Gel'fand, Kapranov and Zelevinsky. Singularities of such functions are discriminants, that is, divisors projectively dual to torus orbit closures. We show that most of these potential denominators never appear in rational hypergeometric functions.
