The authors aim at drawing the attention of researchers to an important question that needs further investigating, namely

Given the difference equation

with an equilibrium solution $\overline{x}$, how nice should $f$ be so that, for $\overline{x}$, local asymptotic stability implies global attractivity?

They also formulate conjectures and pose open problems in this regard in the context of rational difference equations of the form

with nonnegative parameters and with nonnegative initial conditions such that the denominator is always positive.
