Title: Braids, Conformal Module and Entropy

Abstract: I will discuss two invariants of conjugacy classes 
of braids and some of their applications. The first invariant 
is the conformal module which implicitly occurred already in 
a paper of Gorin and Lin in connection with their interest in 
the 13th Hilbert problem. The second is a popular dynamical 
invariant, the entropy. It occurred in connection with 
Thurston's theory of surface homeomorphisms. It turns out that 
these invariants are related: They are inverse proportional.
