Resumen de A note on projection of fuzzy sets on hyperplanes

Heriberto Román Flores, Arturo Flores Franulic

• The aim of this paper is to realize a comparative study between the concepts of projection and shadow of fuzzy sets on a closed hyperplane in a Hilbert space X , this last one introduced by Zadeh in [8] on finite dimensional spaces and recently studied by Takahashi [1,7] in a real Hilbert space X.
