Limiti e analisi non standard
In this note we give a nonstandard characterization of multiple topological operators as sup-min of standard part map.
-limiti e minimi di Pareto
The notion of -limit is extended from the case of functions with values in to the case of those with values in an arbitrary complete lattice and the problem of convergence of Pareto minima related to a convex cone is considered.
