The sixth Bath-Beijing-Paris branching structures meeting was held online, and was an opportunity to discuss a broad family of stochastic models which exhibit branching phenomena, including applications to neutron transport.
As a new feature for this series of meetings, the meeting ran in extended form for five days split into two components.
The first three days were devoted to random branching structures such as branching random walks, fragmentation and coalescence processes, and population models, as well as other probabilistic models.
The last two days were devoted more specifically to an application area of branching structures. For this edition of the workshop, we focussed on recent innovations in the theory of neutron transport and its connection to quasi-stationarity, Monte-Carlo simulation and numerical stochastic methods.
The workshop was moved from its previously scheduled dates of 20-24 April 2020 due to the COVID-19 pandemic, in the hope of holding an in-person event. However, with continued restrictions caused by the virus, especially on international travel, the organisers decided to move the event online.
