Survival of homogeneous fragmentation processes with killing

Abstract: We consider a homogeneous fragmentation process with killing at an exponential barrier. With the help of two families of martingales we analyse the decay of the largest fragment for parameter values that allow for survival. In this respect the present paper is also concerned with the probability of extinction of the killed process.We begin our exposition by briefly reviewing what is meant by a homogeneous fragmentation process, thereby introducing some notation.

“…Throughout this paper we assume that d = 0 as well as ν(s ∈ S : s 2 = 0) = 0. In view of the forthcoming assumption (4) this enables us to resort to the results of [19], where the same assumptions are made. Let us mention that the assumption d = 0 does not result in any loss of generality, see Remark 1.…”

“…For the time being, let x ∈ R ∞ . In this paper we are concerned with a specific procedure of killing blocks of Π, see Figure 1(a), that was introduced in [19]. More precisely, for c > 0 a block Π n (t) is killed, with cemetery state ∅, at the moment of its creation t ∈ R + 0 if |Π n (t)| < e −(x+ct) .…”
