From October 27 til November 1, Peter Beelen visited Prof. Massimo Giulietti and his team at the Università degli Studi di Perugia in Italy. During the visit he finished an article with Maria Montanucci, who visited DTU as a guest PhD in 2017. Directly after the visit, Maria started as a postdoctoral researcher at the University of Padua.
In the joint article certain subfields are described of the new maximal function fields found by Maria and Peter in 2017. Such subfields are of interest, since by a result of Serre, they are maximal as well. The article has been submitted to the journal Finite Fields and Their Applications. A preprint is available here.
