“…As a result of such irreducible dichotomy, one is forced to study indirectly features and behaviour of the solution mapping, whose analytic form remains hidden, by performing proper inspections of the given equation data. Roughly speaking, this is the spirit essentially shared by many implicit function and multifunction theorems recently established in different areas of analysis (see [6,8,11,20,21,26,34,36], just to mention those works cited in the present paper for other purposes). The case of parameterized generalized equations 1 in variational analysis makes no exception.Given a set-valued mapping F : P × X −→ 2 Y and a functon f : P × X −→ Y , by parameterized generalized equation the following problem is meant:According to the nowadays vast literature devoted to such subject, parameterized generalized equations are formalized in several different fashions.…”
