DESCRIPTION:Let A be a finite set. A partial clone on A is a set of partia
l functions closed under composition and containing all projection functio
ns on A. We survey some results in the theory of partial clones. In partic
ular\,\n\n1- we show the link between The Erdös-Faber-Lovsáz conjecture
for graphs and combinatorial descriptions of some maximal partial clones\,
\n\n2- we give a complete classification of certain intervals of partial c
lones\, that solves an open problem by D. Lau.\n\nThese results were obtai
n in collaboration with C. Tardif (1) and M. Couceiro\, K. Schölzel and T
. Waldhauser (2).\n\nhttps://indico.math.cnrs.fr/event/1140/
