Abstract
Dilatively stable processes generalize the class of infinitely divisible self-similar pro- cesses. We reformulate and extend the definition of dilative stability introduced by Igl´oi (2008) using characteristic functions. We also generalize the concept of aggregate similar- ity introduced by Kaj (2005). It turns out that these two notions are essentially the same for infinitely divisible processes. Examples of dilatively stable generalized fractional L´evy processes are given and we point out that certain limit processes in aggregation models are dilatively stable.
