WebbThe spatial logistic model is a system of point entities (particles) in Rd which reproduce themselves at distant points (dispersal) and die, also due to competition. The states of such systems are probability measures on the space of all locally finite particle configurations. In this paper, we obtain the evolution of states of ‘finite systems’, that is, … WebbIn such chapter, we briefly (and somewhat heuristically) introduce equilibrium chemistry and equilibrium statistical mechanics, explaining the links between these two theories. We also provide an informal discussion about the mini der Waals–Maxwell theory of condensation and of the paramagnet/ferromagnet form transition.
