Finite Logarithmic Order Meromorphic Solutions of Complex Linear Delay-Differential Equations
In this article, we study the growth of meromorphic solutions of linear delay-differential equation of the form [\ \sum_{i=0}^{n}\sum_{j=0}^{m}A_{ij}(z)f^{(j)}(z+c_{i})=F(z),/] where Aij(z) (i = 0, 1, ..., n, j = 0, 1, ..., m, n, m ∈ N) and F(z) are ...

A Cubic Hamiltonian System with Meromorphic Solutions [PDF]
Consider the system of equations \[ \dot{q}=p^2+zq+\alpha,\quad \dot{p}=-q^2-zp-\beta,\quad\alpha,\beta\in\mathbb{C}. \] It is a Hamiltonian system with the Hamiltonian \[ H=\frac{1}{3}(q^3+p^3)+zpq+\alpha p+\beta q. \] In the paper it is proved that this system has the Painlevé property. Actually this result follows from a general result of the paper [

All Admissible Meromorphic Solutions of Hayman's Equation [PDF]
We find all non-rational meromorphic solutions of the equation $ww"-(w')^2=α(z)w+β(z)w'+γ(z)$, where $α$, $β$ and $γ$ are rational functions of $z$. In so doing we answer a question of Hayman by showing that all such solutions have finite order. Apart from special choices of the coefficient functions, the general solution is not meromorphic and ...

MEROMORPHIC SOLUTIONS OF q-DIFFERENCE EQUATIONS
Let \(q\) be a complex number with \(0 < | q| < 1\), and let \(a(z)\), \(b(z)\) and \(c(z)\) be polynomials having no common zeros. The authors treat a \(q\)-difference equation of first order \[ a(z)f(z) =b(z)f(qz)+c(z),\tag{1} \] in which they assume that \(a(0)\neq 0\), \(b(z)\not\equiv 0\) and \(A + B \geq 1\), where \(A =\text{deg\,}a(z)\), \(B = \

Abelian number fields with frobenian conditions
Abstract We study the distribution of abelian number fields with frobenian conditions imposed on the conductor. In particular, we find an asymptotic for the number of abelian field extensions of a number field k$k$ whose conductor is the sum of two squares. We also discuss an application of the Brauer group of stacks to quadratic number fields.

An Extended Complex Method to Solve the Predator–Prey Model
Through transformation and utilizing a novel extended complex method combining with the Weierstrass factorization theorem, Wiman–Valiron theory and the Painlevé test, new non-constant meromorphic solutions were constructed for the predator–prey model ...
