David Bang

I am a third-year PhD student in the Warwick Maths and Stats CDT programme at the Department of Statistics of the University of Warwick under the supervision of Professor Aleksandar MijatovićLink opens in a new window. My main interests are in applied and theoretical probability. Right now my main work is on Lévy processes and concave majorants (convex minorants).

Talks at Conferences and Workshops:
21st April 2022: Asymptotic length of the concave majorant of a Lévy process, Isaac Newton Institute for Mathematical Sciences, Optimal control and fractional dynamics Workshop, (FD2W03). The talk can be watched here: https://youtu.be/MT7X3y-ZtJ0?t=2107.
