Sharp asymptotics for the free energy of 1+1 dimensional directed polymers in an infinitely divisible environment
Frederique Watbled1

We give sharp estimates for the free energy of directed polymers in random environment in dimension 1+1. These estimates were known for a gaussian environment, we extend them to the case where the law of the environment is infinitely divisible.
