• #### Theoretical Analysis and Simulation Methods for Hawkes Processes and their Diffusion Approximation ﻿

[OWP-2020-09] (Mathematisches Forschungsinstitut Oberwolfach, 2020-03-30)
Oscillatory systems of interacting Hawkes processes with Erlang memory kernels were introduced in Ditlevsen and Löcherbach (2017). They are piecewise deterministic Markov processes (PDMP) and can be approximated by a ...
• #### Unexpected Properties of the Klein Configuration of 60 Points in $\mathbb{P}^3$ ﻿

[OWP-2020-19] (Mathematisches Forschungsinstitut Oberwolfach, 2020-10-07)
Felix Klein in course of his study of the regular and its symmetries encountered a highly symmetric configuration of 60 points in $\mathbb{P}^3$. This configuration has appeared in various guises, perhaps post notably as ...
