What’s New

Sven Puchinger, Postdoc

Postdoc Sven Puchinger started

Johan S. R. Nielsen No Comments

The Algebra group has a great new addition: Postdoc Sven Puchinger started 1st October on his 2-year H. C. Ørsted fellowship. Sven Puchinger has his PhD Degree from the University of Ulm under the supervision of Martin Bossert (where Johan was also a postdoc in 2014-2015), and he spent the last 1,5 years as a postdoc at Technical University of Munich.

His research interests are broadly within algebraic coding theory, from new code constructions to decoding and fancy applications. Sven already has numerous joint papers with Johan and Peter, and we foresee that his postdoc here will be very fruitful.

Coding Theory Cartoon

Grigory and Leonardo created this great cartoon explaining the principles and importance of coding theory – illustrated by a cross-galactic love story!

The video was made as their contribution to the DTU Compute PhD Bazaar.

SIAM/AG 2019

Johan S. R. Nielsen No Comments

Johan and Grigory participated in the conference SIAM Applied Algebraic Geometry 2019. The conference had many talks on computer algebra, coding theory and cryptography. Johan gave a talk entitled “Decoding of Gabidulin codes and friends using row reduction of skew polynomial matrices”.

AGCT 2019

Peter Beelen No Comments

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.

Workshop on Polynomials and Curves over Finite Fields

Peter Beelen No Comments

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 .

Antalya Algebra Days

Peter Beelen No Comments

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.

Maria Montanucci, Assistant Professor at the Algebra group

Maria Montanucci joins the algebra group

Peter Beelen No Comments

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.

Visit by professor Trygve Johnsen.

Peter Beelen No Comments

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.

Research visit by Sven Puchinger

Johan S. R. Nielsen No Comments

The Algebra group was visited late January 2019 by Sven Puchinger who is a postdoc at TU München. Sven has visited us before, and is also a former colleague of Johan at Ulm University in 2013-2014. Sven has numerous research papers jointly written with Johan and Peter.

During the visit, we mostly discussed Twisted Reed-Solomon codes: these are optimal codes (MDS) which are constructed by slightly “twisting” a Reed-Solomon code by carefully adding a monomial to the evaluation polynomials. We proposed the codes in an ISIT paper in 2017, and in 2018 we derived more properties and proposed them for quantum-computer-resilient cryptography. After Sven’s visit, we now have new observations which we will write down in an upcoming paper.

Sven also gave a very nice talk entitled “On Decoding and Applications of Interleaved Gabidulin Codes”.

Leonardo Landi, PhD at Algebra Group at DTU

New PhD Student: Leonardo Landi

Johan S. R. Nielsen No Comments

Our new PhD student Leonardo Landi started 1st January 2019! Leonardo holds a Master’s degree from the University of Parma, Italy. His PhD project has the tentative title “Curves and Error-Correction”: the aim is to get a better insight in the structure of algebraic geometry codes constructed using towers of function fields.
