Can Pourciau's open mapping theorem be derived from Clarke's inverse mapping theorem easily?
Essentially, the authors study the possibility to deduce a suitable open mapping theorem (defined by \textit{B. H. Pourciau} [J. Optim. Theory Appl. 22, 311--351 (1977; Zbl 0336.26008)]) from another appropriate inverse mapping theorem (set up by \textit{F. H. Clarke} [Optimization and nonsmooth analysis. John Wiley, New York, NY (1983; Zbl 0582.49001)]).
