Title: In search of new hereditarily just infinite groups
Abstract: An infinite group is said to be just infinite if it has no infinite proper quotient. A just infinite group is hereditarily just infinite if each of its finite index subgroups is just infinite.
Hereditarily just infinite groups are – as of today – quite mysterious. In this talk we will survey what is know about them and I will present some work in progress with G. Fernandez-Alcober and M. Noce about hereditarily just infinite groups representable as self-similar subgroups of rooted trees.
