Students of Mathematics and Computer Sciences Josse van Dobben de Bruyn, Mathijs van Nes and Bas Nieuwenhuizen will represent Leiden University in the World Finals Programming 2013 in St. Petersburg. From 30 June to 4 July, the 240 smartest programmers from universities around the world will come together at this Championship. The team ‘Geen Syntax’ (‘No Syntax’) is the only Dutch team represented. Their goal is to end in the top 10 of the world and they are very well prepared. The team scored a second place in the European preliminaries. For the final in St. Petersburg they will be stuck to their chairs for hours to solve ten complex sums. "We all know what our tasks are. One analyzes, the other counts and the third fills in. It is all about the good answers.” We wish you lots of success and of course a Russian medal!
On Tuesday, June 11th at 8:45 AM Ariyan Javan Peykar will defend his PhD thesis, entitled 'Arakelov invariants of Belyi curves'. The defense will take place under the auspices of the Erasmus Mundus ALGANT consortium which, in this case, has led to a collaboration (cotutelle) between Leiden and Université Paris-Sud/Orsay. The defense will take place in the Academy Building, Rapenburg 73. Promotors are Bas Edixhoven and Jean-Benoît Bost (Université Paris-Sud/Orsay), Robin de Jong is copromotor.
Please see here for more information, and the PhD thesis.
Andrea Siviero is to complete his dissertation within the Erasmus Mundus Algant-PhD-programme within the project 'Realizable Classes for non-abelian extensions', under the supervision of Dr. Bart de Smit (Leiden) and Prof. Boaz Erez (Bordeaux). The title of his thesis is: "Class invariants for tame Galois algebras". The defense of his thesis will take place on 26 June 2013 on 08h45 in the ‘Academiegebouw’ in Leiden. The Algant Consortium consists of 8 universities on 4 continents that offer a joint doctorate programme in pure mathematics, with a strong emphasis on Algebra, Geometry and Number Theory.
Ronald Cramer, Professor at the Mathematical Institute of Leiden University and researcher and head of the research group Cryptology at ‘Centrum Wiskunde & Informatica (CWI), the national research center for mathematics and computers science in the Netherlands, is appointed as a member of the Royal Dutch Academy of Sciences (KNAW). Academy members are prominent scientists who are nominated by fellow researchers inside and outside the Academy. Earlier appointed KNAW members from the Mathematical Institute are Rob Tijdeman, Bert Peletier, Willem van Zwet, Jaap Murre, Hendrik Lenstra, Bas Edixhoven, Jacqueline Meulman, Frank den Hollander, Aad van der Vaart en Richard Gill.
Cramer is engaged with cryptography, the mathematics of digital security which is for example important for internet transactions. The Cramer-Shoup cryptosystem, which he and his American colleague Victor Shoup published, was the first practical system resistant to active attacks. The system became an international standard. Cramer also designed a system for secure collaboration between parties that do not trust each other. The new applications of classical mathematics in cryptography found by Cramer are groundbreaking. Cramer was among the first group of The Young Academy (De Jonge Akademie).
Ronald Cramer: "I am pleased with this honorable membership. As an Academy member I hope to continue my work for the science.”
Frank den Hollander has been elected as Fellow of the Institute of Mathematical Statistics. A fellowship is a way of honoring the outstanding research and professional contributions of the members, contributions which give IMS a leading role in the field of statistics and probability. The IMS is an international professional and academic society devoted to the development, distribution, and application of statistics and probability. The Institute currently has about 4,500 members in all parts of the world. The Leiden University statisticians Richard Gill, Aad van der Vaart and Willem van Zwet were already appointed as Fellow of the IMS.
Vietnamese mathematician Dung is the first to complete his dissertation within the Erasmus Mundus Algant PhD-programme, under the supervision of Prof.dr.Hendrik Lenstra. The defence of his thesis ‘Profinite groups with a rational probabilistic zeta function’ will take place on 14 May 2013 on 13h45 in the ‘Academiegebouw’ in Leiden. The Algant Consortium consists of 8 universities on 4 continents that offer a joint doctorate programme in pure mathematics, with a strong emphasis on Algebra, Geometry and Number Theory. 'The Algant programme was a golden opportunity', says Duong Hoang Dung. ‘Doing a PhD in Vietnam is very difficult. I would not get a grant there and in addition to paying for the tuition fees, I would also have to work very hard to pay for my living costs while doing research. This means there would be much less time for the thesis. I want to use my new knowledge to help develop maths in Vietnam. In Vietnam it is almost impossible to visit international conferences abroad, or to have easy access to the latest publications in mathematics'.
