Periodicities in Nonlinear Difference Equations
Sharkovsky's Theorem, Li and Yorke's "period three implies chaos" result, and the (3x+1) conjecture
are beautiful and deep results that demonstrate the rich periodic character of first-order, nonlinear difference equations.
To date, however, we still know surprisingly little about higher-order nonlinear difference equations.
