Some Remarks on Age Dependent Branching and Super Processes

Siva Athreya

In this talk we will discuss an age dependent branching particle system and its rescaled limit, the super-process. The above systems are non-local (i.e. the position of the offspring is not the same as that of the parent) in nature and some specific difficulties arise in this setting. We shall begin with a review of the literature, discuss the above difficulties and present some new observations.
