On the Recursive Sequence xn 1 A x p n − 1 / x q n

A Note on the Nonlinear Recurrence xn + 1 xn − 1 − x 2 n = A Michele Elia

The existence and uniqueness of the integral solutions of xn+1xn−1− xn = A are examined and some open questions settled. Mathematics Subject Classification: 39A99, 12F05, 11B39

Interaction of alanine with lithium. I- the alanine–Li -n (H20) n (0–2) complexes

The energy minima of systems made of an alanine molecule, a lithium cation and a various number of watermolecules have been determined with the help of quantum mechanical computations at the B3LYP DensityFunctional Theory level of computation and the standard 6-311++G (d,p) basis set. Several structures, close inenergy are found and the presence of one or two water molecules around the cation m...

Semigroups Satisfying xm+n = xn

We summarize recent results on semigroups satisfying the identity x = x, for n 0 and m 1, and some rewrite techniques that have contributed to their investigation.

On the nature of solutions of the difference equation $mathbf{x_{n+1}=x_{n}x_{n-3}-1}$

We investigate the long-term behavior of solutions of the difference equation[ x_{n+1}=x_{n}x_{n-3}-1 ,, n=0 ,, 1 ,, ldots ,, ]noindent where the initial conditions $x_{-3} ,, x_{-2} ,, x_{-1} ,, x_{0}$ are real numbers.  In particular, we look at the periodicity and asymptotic periodicity of solutions, as well as the existence of unbounded solutions.
