SUMMARY: (...): Density of rational languages under invariant measures
DESCRIPTION:: The notion of density for languages was studied by Schützenb
 erger in the 60s and by Hansel and Perrin in the 80s. In both cases\, the 
 authors focused on densities defined by Bernoulli measures. In this talk\,
  I will present new results about densities of regular languages under inv
 ariant measures of minimal shift spaces. We introduce a compatibility cond
 ition which implies convergence of the density to a constant which depends
  only on the given rational language. This result can be seen as a form of
  equidistribution property. The compatibility condition can be stated eith
 er in terms of return words or of a skew product. The passage between the 
 two forms is made more transparent using simple combinatorial tools inspir
 ed by ergodic theory and cohomology. This is joint work with Valérie Bert
 hé\, Carl-Fredrik Nyberg Brodda\, Dominique Perrin and Karl Petersen. .\n
