SECOND-ORDER ASYMPTOTIC EXPANSION FOR THE DISTRIBUTION OF PARTICLES IN A BRANCHING RANDOM WALK WITH A RANDOM ENVIRONMENT IN TIME
Résumé
We consider a branching random walk in which offspring distribution and moving laws both depend on an independent and identically distributed environment indexed by the time. For A ⊂ R , let Z n (A) be the number of particles of generation n located in A. We give the second-order asymptotic expansion for the counting measure Z n (·) with appropriate normalization.
