Xing Zhu, Chuanze Niu
Abstract: The formula of the $p$-adic valuation of the sequence $C_n(l)=\prod_{k=1}^{n}\prod_{j=0}^{l}(2k+2j-1)$ is studied. It is proved that $C_n(l)$ is not a square if $l$ is even and $n\ge \max\{2l,\frac{3l+19}{5}\}$. It is proved also that there are many squares in the sequences $C_n(1)$ and $C_n(3)$, while there are no squares [...] Read more.

In this study, existence of Hopf bifurcations of a n [...] Read more.

Abstract: Abstract In this paper, the global, non-vacuum solutions with large amplitude to the initial-boundary value problem of the one-dimensional compressible Navier-Stokes-Poisson system with viscosity and heat conductivity coefficients are considered. The proof is based on the analysis on the positive lower and upper bounds on [...] Read more.

Abstract: Sequences have been fascinating topic for mathematicians for centuries. The Fibonacci and Lucas sequences are examples of second order recursive sequences. Fibonacci sequence is defined by In recent years, few research scholars have been introduced Fibonacci-Like sequences which are similar to Fibonacci sequences in recur [...] Read more.

Abstract: Free Replication Hull (FRH) is a special case of the CCR DEA problem in which the convexity axiom is excluded from the PPS of the CCR model and the intensity variables are restricted to the whole numbers. In this paper we propose MAJ-FRH, similar to the ranking method in data envelopment analysis proposed by Mehrabian et al [...] Read more.

Abstract: Solutions to the Navier-Stokes equations for the Millenium Prize Problem are provided. These consist of a transient Pile-Up flow. A proof is given to show that the flow functions satisfy the Boundary Conditions at infinity. The proof for the spatial derivatives of velocity, u, and force, f, relies on decomposition of an exp [...] Read more.

Abstract: Rational points on elliptic curves are considered, in the formulation of BSD, and for nonlinear dynamical systems. Method used is the intersection with other curves, for a more general expression of an elliptic curve, known as an extended elliptic curve. It is found that there are elliptic curves with at most 3 rational sol [...] Read more.

Abstract: The article discusses some of the mathematical results widely used in practice which contain the Riemann ζ-function, and, at first glance, are in contradiction with common sense. A geometric approach is suggested, based on the concept of the curvature of space, in which is calculated an algorithm that specifies the represe [...] Read more.
