Branching structures

The sixth Bath-Beijing-Paris meeting

  • 13 Sep 2021, 9.00am to 17 Sep 2021, 5.00pm BST (GMT +01:00)
  • This is an online event.
  • This event is free

The sixth Bath-Beijing-Paris branching structures meeting will be held online, and will be 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 will run in extended form for five days split into two components.

The first three days are 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 are devoted more specifically to an application area of branching structures. For this edition of the workshop, we will focus 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.

For details of previous events, see the webpages of the second, third, fourth and fifth meetings in the series.

Schedule for branching structure days (times are BST, which is UTC+1)

The conference will take place on Gathertown and Zoom. Participants should have received a link to the Gathertown space by e-mail. The talks will take place via Zoom and can be accessed through the Gathertown space or, alternatively, through a link in the same e-mail. If you haven't received the links please contact the organisers.
