Abstract: | This paper investigates properties of a parametric set defined by finitely many equality and inequality constraints under
the constant rank constraint qualification (CRCQ). We show, under the CRCQ, that the indicator function of this set is prox-regular
with compatible parametrization, that the set-valued map that assigns each parameter to the set defined by that parameter
satisfies a continuity property similar to the Aubin property, and that the Euclidean projector onto this set is a piecewise
smooth function. We also show in the absence of parameters that the CRCQ implies the Mangasarian-Fromovitz constraint qualification
to hold in some alternative expression of the set. |
