Éléments ipsoduaux du treillis distributif libre et familles de Sperner ipsotransversales

In this paper, we characterize self-dual elements of a free distributive lattice with n generators by means of a median operation on this lattice. Hence, we obtain a constructive characterization of Sperner's families, for which H is equal to Tr H. We construct some infinite sequences of these families. These results generalize those of N. M. Rivi6re (J. Combinatorial Theory 5 (1968), 229-234) ...

Éléments pour une théorie opérationnelle de l'écriture numérique

The change to digital writing amounts to a reconfiguration which affects the very nature of knowledge. There is a scientific and operational stake in the study of the characteristics inherent to this renewed form of writing, particularly for the design of systems, the analysis of practices and the teaching of digital writing. This paper contributes to such purpose with a theoretical study based...
