Abstract |
The Central Limit Theorem is both one of the most important theorems in probability theory and the foundation of many physical
approaches to the collective behavior of large numbers of bodies in physics. However, it is limited to situations where the degrees
of freedom involved are either independent of each other or only weakly correlated. Cases of strong correlations, encountered for
example in the vicinity of a critical phenomenon, require a different approach, and we will show that the functional renormalization
group is very well suited to this study. A general introduction to this modern version of the renormalization group a la Wilson will
be given in this seminar.
