Rough SDEs and Robust Filtering for Jump-Diffusions
Andrew L. Allan, Jost Pieper, Josef Teichmann
We investigate the existence of a robust, i.e., continuous, representation of the conditional distribution in a stochastic filtering model for multidimensional correlated jump-diff…

Rough Stochastic Analysis with Jumps
Andrew L. Allan, Jost Pieper
We present a new version of the stochastic sewing lemma, capable of handling multiple discontinuous control functions. This is then used to develop a theory of rough stochastic ana…

Magnetic Field Evolution of Hot Exoplanets
Konstantinos Kilmetis, Aline A. Vidotto, Andrew Allan +1
Numerical simulations have shown that the strength of planetary magnetic fields depends on the convective energy flux emerging from planetary interiors. Here we model the interior…
