The Derrida--Retaux conjecture on recursive models

Abstract : We are interested in the nearly supercritical regime in a family of max-type recursive models studied by Derrida and Retaux, and prove that under a suitable integrability assumption on the initial distribution, the free energy vanishes at the transition with an essential singularity with exponent $\tfrac12$. This gives a weaker answer to a conjecture of Derrida and Retaux. Other behaviours are obtained when the integrability condition is not satisfied.
