For the random pinning model with α > 1, it is also shown in [13] that the partition function under weak coupling converges, in the continuum limit, to the exponential of a

This paper deals with two pinning models with Markov disorder, and is organized as follows: in a first part we will recall notations and general facts on the model, and give an

The appropriate measure for M combined with a "global" maximum entropy hypothesis, leads to a joint distribution for these levels of the same form as the

Existence of the Lyapunov exponent for the model equation We now formulate our results on the pointwise existence of the right Lyapunov exponent γ + (θ) for the model equation (5);

We study several new invariants associated to a holomorphic projective struc- ture on a Riemann surface of finite analytic type: the Lyapunov exponent of its holonomy which is

We study the persistence exponent for random walks in random sceneries (RWRS) with integer values and for some special random walks in random environment in Z 2 including random
