Voir la notice de l'article provenant de la source Theory and Applications of Categories website

Two proofs of the exponentiability of perfect maps are presented and compared to two other recent approaches. One of the proofs is an elementaryapproach including a direct construction of the exponentials. The other, implicit in the literature, uses internal locales in the topos of set-valued sheaves on a topological space.
