Abstract
Galois groups of p-class towers of number fields have long been a mystery, but recent calculations have led to glimpses of a rich theory behind them, involving Galois actions on trees, families of groups whose derived series have finite index, families of deficiency zero p-groups approximated by p-adic analytic groups, and so on.
