Postdoc Vincent Neiger just got a paper accepted in the prestigious Journal of Complexity. The paper, with the title “Fast, deterministic computation of the Hermite normal form and determinant of a polynomial matrix” is coauthored with George Labahn and Wei Zhou. In the paper a fast and deterministic algorithms is given to compute the determinant and Hermite normal form of a nonsingular square matrix of univariate polynomial over a field.
A preprint of the paper can be found here.
Maria Montanucci a Ph.D. student in Mathematics at Università degli Studi della Basilicata (Potenza, Italy) will visit the algebra group from 1 April – 31 May. Her advisior is Prof. Gábor Korchmáros who has done excellent work in the theory of algebraic curves in positive characteristic. Maria obtained her Master degree in 2015 at Università degli Studi di Perugia under the supervision of Prof. Massimo Giulietti, another leading expert in the theory of algebraic curves. We look forward to her visit.
The coming three weeks the algebra group will be host for guest Ph.D. student Élise Barelli. She is part of the project team Grace at Inria Saclay, France. Her supervisor is Alain Couvreur, who has visited the algebra group in the past.
While at DTU, Élise will work on algebraic curves with many automorphisms with a view to their application in cryptosystems.
The Algebra group at DTU just submitted 3 papers to the prestigious conference International Symposium in Symbolic and Algebraic Computation 2017.
The papers were:
Popov Form Computation for Matrices of Ore Polynomials, Mohamed Khochtali, Johan Rosenkilde, Arne Storjohann.
Computing canonical bases of modules of univariate relations, Thi Xuan Vu, Vincent Neiger
The papers are now undergoing review, and we will get news about acceptance or not by mid-April.
The Algebra group at DTU has just submitted 2 papers to the prestigious International Symposium in Information Theory 2017 conference, held in June this year. The papers are:
Decoding of Interleaved Reed-Solomon Code using Improved Power Decoding, Sven Puchinger, Johan Rosenkilde. arXiv pre-print.
The papers are now undergoing review, and we will get news about acceptance or not by the end of March.
From the 9th of January till the 4th of February Peter Beelen will visit the Department of Mathematics at IIT-Bombay as visiting professor. During this visit he will give several lectures on algebraic aspects of coding theory as well as conduct research with his host Sudhir R. Ghorpade.
Today postdoc Vincent Neiger started in the algebra group. He is supported for two years by the H.C.Ørsted foundation and will work on fast algorithms on matrices with polynomial entries.
Today a workshop took place at DTU in connection to the FNU-project “How secret is a secret?”. Apart from DTU, the participants came from AU and AAU. A short program of the workshop can be found here.
Nurdagül Anbar’s position as postdoctoral researcher in the algebra group finished on the 1st of October after having worked with us for two years.
She now starts a postdoc position at the University of Magdeburg. We will miss her drive, ideas and energy and wish her all the best in her future career!
Her project Curves with many rational points was supported by the HCØrsted COFUND Postdoc programme. Nurdagül has been a successful researcher, having contributed significantly to five project-related articles (and several others besides). Of these five, one has appeared electronically in the Journal of Number Theory, three have been accepted, and one is currently under review.
A workshop on the mathematics of theoretic cryptography organized by NUS and NTU will be held in Singapore from 26th till the 30th of September. Peter Beelen is a key-note speaker for this workshop and will give an overview talk on towers of function fields and their uses in coding theory.
