A continuum individual based model of fragmentation: dynamics of correlation functions

Agnieszka Tanaś


An individual-based model of an infinite system of point particles in Rd is proposed and studied. In this model, each particle at random produces a finite number of new particles and disappears afterwards. The phase space for this model is the set Γ of all locally finite subsets of Rd. The system's states are probability measures on  Γ the Markov evolution of which is described in terms of their  correlation functions in a scale of Banach spaces. The existence and uniqueness of solutions of the corresponding evolution equation are proved.


Configuration space; individual-based model; birth-and-death process; correlation function; scale of Banach spaces; Ovcyannikov method.
