DESCRIPTION:Dealing with random infinite graphs inevitably leads to a stud
 y\nof invariance properties of the associated measures on the space of\nro
 oted graphs. In this context there are two natural notions: that of\nmeasu
 res invariant with respect to the "root moving" equivalence relation\n(bas
 ed on ideas from ergodic theory and geometry of foliations) and that of\nu
 nimodular measures recently introduced by probabilists. I will give a\nbri
 ef survey of the area\, and\, in particular\, clarify the relationship\nbe
 tween these two classes of measures.\n
