SUMMARY:Timelines Analysis and competition over popularity\, influence and
 visibility in social networks.
DESCRIPTION:The major social networks use timelines to display content that
 a user receives from those sources that he follows. A content that arrives
 at a timeline is placed at the top of the list and each other content is
 pushed down by one step. If the timeline is finite (as in twitter) then
 this causes the last element in the timeline to be pushed out. Moreover\,
 the lower the content is on the timeline the smaller its influence is. In
 this talk we shall first present analysis of the timeline process and of
 the probability to be visible on the timeline. We shall further describe
 the influence process of content which takes into account not only the
 location on the timeline but also aging of content. We shall then study the
 impact of the burstiness of the arrival of contents on the timeline
 process. We shall finally introduce game theoretical models to describe the
 competition over popularity and over visibility of content in the timeline.
 We shall study two specific game theoretic problems. The first is a timing
 game: when is it best to send a content. The second is a resource
 allocation game for optimal control of the flow of content.The work
 describes ongoing collaborative work with many woauthors: Alexandre
 Reiffers\, Nahum Shimkin\, Anurag Kumar\, Yezekael Hayel and others.
