%X A Teichm¨šller like structure on the space of d-degree holomorphic maps on the circle S1, marked by conjugations to the map z   zd, can be defined. Here we introduce a definition of free energy associated to this kind of dynamics as an invariant of equivalence classes in the Teichm¨šller space. This quantity encodes a length spectrum of rotation cycles in S1.
