✦ Synopsis

We study the time asymptotics of solutions to the diffusive fragmentation-coagulation system which we derived in a previous work [J.-E Collet, E Poupaud, Transp. Theory and Stat. Phys. 25 (3-5) (1996) 503-513]. In the case where a detailed balance equilibrium exists, we derive convergence to such a state by using a careful analysis of the free energy dissipation rate of the system. In the case where no detailed balance equilibrium exists, we show the existence of an attractor by using classical energy inequalities and some estimates on higher moments of the solution.

New sufficient conditions for the competitive exclusion of a few species in some Lotka-Volterra systems are proved. Also an approach based on some results of the matrix Riccati equations and some ideas of the asymptotic methods is developed. In addition, conditions for the existence of finite escape

The aim of this paper is to investigate the behaviour as tP R of solutions to the Cauchy problem , where '0 is a fixed constant, t\*0, x31L. First, we prove that if u is the solution to the linearized equation, i.e. with β€’ F(u),0, then u decays like a solution for the analogous problem to the heat
