Conditioned real-valued self-similar Markov processes

Joint work with Andreas Kyprianou(My PhD supervisor), Victor Rivero

We will be looking to condition a self-similar Markov process to stay in a particular set.

General theme of this problem : Given a martingale that vanished outside a given set. Then, try to show that the tail distribution of the exit time behaves similar to the martingale(normally with the help of Markov Renewal Theorem). Then, deduce that the conditioning actually corresponds to the process Doob-h transformed be the martingale.

Predicting Geomagnetic Storms with transition probabilities

Joint work with Nicole Augustin, Andrea Lelli



Electromagnetic storm is a temporary disturbance in the Earth's magnetic fields caused by the activities of the Sun. This could be modelled simply as a discrete time Markov Chain

However, we know that the Geomagnetic storms are caused directly by the Sun. We will be looking to include the information of the Sun activity into our model. See ITT presentation slides

This work is followed from the ITT3 as a project introduced by the Met Office.
