Algebro-Geometric Solutions for a Discrete Integrable Equation
Discrete Dynamics in Nature and Society, 2017 With the assistance of a Lie algebra whose element is a matrix, we introduce a discrete spectral problem. By means of discrete zero curvature equation, we obtain a discrete integrable hierarchy. According to decomposition of the discrete systems, the new

The Numerical Solution of the L-Fractional Abel Differential Equations
Journal of Mathematical Sciences and ModellingIn this paper, approximate solutions of the L (Leibniz)-fractional Abel differential equations of the first and second kind are computed by using the shifted Morgan-Voyce (SMV) polynomials. Fractional derivatives are defined in the Leibniz sense. Firstly,

Journal of the Royal Anthropological Institute, EarlyView.Our current understanding of the origins of Homo sapiens is limited, in part, by the fragmented fossil record from Late Pleistocene and early Holocene Africa. Here, we re‐examine the Kabua 1 cranium, an enigmatic and little‐studied Kenyan fossil discovered in the 1950s. We compare virtual reconstructions created previously by our team with a wide range

On the composition conjectures
Electronic Journal of Differential Equations, 2003 We describe a class of polynomials that satisfy the composition conjecture for the moments. We also show that the composition conjecture for the moments is not weaker than the composition conjecture for a center.

A (2 + 1)-Dimensional Integrable Breaking Soliton Equation and Its Algebro-Geometric Solutions
MathematicsA new (2 + 1)-dimensional breaking soliton equation with the help of the nonisospectral Lax pair is presented. It is shown that the compatible solutions of the first two nontrivial equations in the (1 + 1)-dimensional Kaup–Newell soliton hierarchy ...

Some New Results on Abel Equations
Journal of Mathematical Analysis and Applications, 2001 For Abel's differential equation \(dr/dt=a(t)r^2+b(t)r^3,\) \(t\in[t_0,t_1],\) it is said that the solution \(r=0\) is a center if for \(c\) small enough, the solution passing for \(r=c\) when \(t=t_0,\) \(r(t,c),\) also satisfies \(r(t_1,c)=c.\) The aim of this paper is to study conditions for Abel's differential equation to have a center at \(r=0 ...

Global Policy, EarlyView.ABSTRACT This article explores the current controversies surrounding the European Ariane launcher and its implications for the future of European space governance. The Ariane program, historically a symbol of European technopolitical integration, faces mounting challenges due to delays, rising costs and increasing competition from private actors like ...
