Abstract :
Multiplicative
chaos is a theory developed by Kahane in the eighties. It deals with
multiplicative processes generating
random
measures with nontrivial multi fractal properties. These measures have recently
played prominent role in models
of
two-dimensional quantum gravity. They provide also simple models of spin glass
phase transition which occurs
as a model
parameter (“temperature”) is varied. I will review the basic theory of
multiplicative chaos and discuss some
recent
results on the critical and low temperature phase.
