In the period January 6-17, Peter visited Tromsø (Norway), where the Arctic University of Norway is located. His host, Prof. Trygve Johnsen has visited the algebra group in the past during his sabattical. During Peter’s visit, he finished two papers and initiated a new one, so the visit was very productive!
Peter and Grigory participated in the workshop MWCC in the period July 15-16. In this workshop experts from all over the world shared their latest insights on codes and their applications in cryptography. Peter gave a talk on his work with postdoc Prasant Singh on the decoding of codes from Grassmann varieties. Grigory presented a poster on the fast encoding of AG codes.
Peter Beelen participated in the biannual AGCT conference (10-14 June 2019) in CIRM, Luminy, France. The initials of this conference refer to Arithmetic, Geometry, Cryptography and Coding Theory. Invited researchers from all over the world meet in this conference to discuss recent developments on the interplay of arithmetic, geometry and their applications in cryptography and coding theory. The conference center is located near the famous Calanques, a natural park near the coast of the Mediterranean sea.
On the 20-22 May, a workshop organized by Nurdagül Anbar, Alp Bassa, Peter Beelen and Sudhir Ghorpade took place at Bogazici University and Sabanci University, Istanbul, Turkey. The topic of the workshop was polynomials and curves over finite fields. From the algebra group, apart from Peter, Maria Montanucci and Prasant Singh participated .
Peter Beelen and Maria Montanucci from the algebra group have visited the Antalya Algebra Days, which this year took place in the Nesin mathematical village in Turkey from the 15th till the 19th of May. Peter gave a talk about his recent research on generalized Hamming weights of Reed-Muller like codes, some of which the carried out together with former postdoc Mrinmoy Datta.
On the 1st of April 2019, Maria Montanucci joined the algebra group in the section for mathematics at DTU Compute as assistant professor. We all wish her welcome!
Maria studied mathematics at the Universitá degli Studi di Perugia in Italy, obtaining her bachelor’s degree cum laude in 2013 and her master’s degree cum laude in 2015. From 2015-2018, she did her PhD under the supervision of Prof. G. Korchmáros at the Università della Basilicata, Italy. After this she was a postdoc at the University of Padua from November 2018 – February 2019, where she worked with Prof. Corrado Zanella.
Today, Peter gave the inaugural lecture for a conference celebrating the influence of Ruud Pellikaan in mathematics on the occasion of his retirement. Ruud Pellikaan was Peter’s PhD supervisor and it was a great pleasure for him to give an overview of Pellikaan’s contributions to mathematics. We wish Ruud a happy retirement!
Prof. Trygve Johnsen from The Arctic University of Norway will visit the algebra group in the section for mathematics at DTU Compute in the coming three months. He is currently on a sabbatical and fortunately for us, he chose DTU as one of the universities he would like to visit. During his stay, he will primarily work with Peter Beelen and Prasant Singh on Grassmann and Schubert codes.
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.
On October 15, PhD student Grigory Solomatov joined our team! Grigory did a dual master at NTNU and DTU. In the coming three years, he will work on the decoding of AG-codes. His project is an important part of the FNU-project “Correcting on a Curve”.
