Abstract:
The paper deals with Image Space Analysis for constrained extremum problems having infinite dimensional image. It is shown
that the introduction of selection for point- to-set maps and of quasi-multipliers allows one to establish sufficient optimality
conditions for problems, where the classic ones fail.
