CARACTERISATION DES RELATIONS BINAIRES FINIES D-DEMI-RECONSTRUCTIBLES
Given a binary relation R of basis E, we define its dual R*by R* (x, y) = R(y, x). A relation R is self-dual if it is isomorphic to R*. A binary relation R' is hemimorphic to R, if it is isomorphic to R or to R*. A binary relation R is d-half-reconstructible if it is determined by its restricti...
