Third order difference equations with two rational integrals

Journal of Physics A: Mathematical and Theoretical, 2009
A systematic investigation to derive three-dimensional analogs of two-dimensional Quispel, Roberts and Thompson (QRT) mappings is presented. The question of integrability of the obtained three-dimensional mappings with two independent integrals is also analyzed.

On the oscillation of third order nonlinear difference equations

Journal of Applied Mathematics and Computing, 2009
The authors obtain some new oscillation criteria for the third-order nonlinear difference equations \[ \Delta^2\left((\Delta x(k))^\alpha/a(k)\right)+q(k)\,f(x[g(k)])=0 \] and \[ \Delta^2\left((\Delta x(k))^\alpha/a(k)\right)+q(k)\,f(x[g(k)])+q(k)\,h(x[\sigma(k)])=0. \] Here, \(\alpha\) is the ratio of two positive odd integers, \(\{a(k)\},\; \{p(k)\}\)
