Title: In search of new hereditarily just infinite groups

Abstract: An infinite group is said to be just infinite if it has noinfinite proper quotient. A just infinite group is hereditarily justinfinite if each of its finite index subgroups is just infinite.
Hereditarily just infinite groups are – as of today – quitemysterious. In this talk we will survey what is know about them and Iwill present some work in progress with G. Fernandez-Alcober and M.Noce about hereditarily just infinite groups representable asself-similar subgroups of rooted trees.
