In this paper we describe some recent results on equilibrium wetting and contact angles and on the dynamics of wetting. We discuss analytically a model with Langevin dynamics and study another model with stochastic dynamics using computer simulation techniques. Both models exhibit a precursor...

In this paper, we study a fourth order semilinear parabolic equation on the infinite real line. We show that in a certain parameter range, this equation has propagating front solutions (solutions tending to 0 at + ∞ and advancing to the right with a speed c) which leave behind them a periodic...

The aim of this paper is to explain why Statistical Physics can help understanding two related linguistic questions. The first question is how to model first language acquisition by a child. The second question is how language change proceeds in time.
