The criterion turns out to be a generalization and improvement over an earlier criterion due to Kar and Singh. An example showing the effectiveness of the criterion is given. A graphical interpretation of a simplified version (involving one free parameter) of the criterion is discussed.eninfo:eu-repo/semantics/closedAccessasymptotic stabilitydifference equationsdiscrete-time dynamical systemslimit cyclesnonlinear difference equationsnonlinear systemsArticleQ3Q3141212551265WOS:0002602124000031
