Please attend the talk.
The talk would be a nice example how mathematics can model a
real-world phenomenon.

Thanks

> We study SIR epidemics on directed random graphs with independent edges (BJR - graphs) and show that twitter cascades can well be described that way. The class of random graphs which we are using for approximation twitter graphs are directed versions of random graph models first introduced by Bollobas, Janson and Riordan a decade ago. The most satisfactory proxy is obtained by BJR models with two dimensional ground space for node values, where the two values correspond up to a normalization factor to the expected in - and outdegree of nodes. A striking finding is the possible dichotomy between total outbreak probability and prevalence of an epidemic outbreak. In directed BJR graphs these two quantities coincide whereas in directed graphs the difference between these two quantities can be arbitrary close to plus or minus one.
