Sunto

Si illustrano la condizione di Opial e la nozione di centro asintotico e si mostra come queste possano essere utilizzate nella teoria dei punti fissi per ottenere risultati di esistenza e di approssimazione.

Summary

Opial condition and asymptotic center are presented. It is shown how they can be useful, in the fixed point theory, to obtain either existence or approximation results.
