Conference "Algorithms and Arithmetic"

The FrenchRussian Poncelet Laboratory organizes a conference on "Algorithms and Arithmetic", Mai 1719, 2010, to take place in the Independent University of Moscow.
Regarding the recent development of information technology, algorithms are nowadays important tools which bridge questions in various mathematical areas, and, especially number theory, with applications in everyday life. One example is of course cryptography which is becoming today a more and more important topic and whose main goal is to develop algorithms to solve natural questions in arithmetic (such as factorization or discrete logarithm problem). Nevertheless it would be unfair to limit algorithms in number theory just to cryptography. Just regarding any symbolic computation software (like Pari, Magma, Sage), one can see that there exists a real desire to manipulate on computers a large family of mathematical objects (sometimes very abstract) coming from number theory: number fields, padic numbers, Galois groups, schemes, modular forms, etc. Of course, such tools are very important also for theorists for instance because they help them everyday to easily test conjectures.
The mail goal of this conference is to give an overview of the role of algorithmic in current research in arithmetic. Since it is of course not reasonable to address all subjects in just one week, we have decided to only focus on the two following ones.
For each subject, we plan to devote one halfday (or, if necessary, one day) to survey talks. Several research talks will then follow.
The conference benefited from the support of the EADS Foundation Chair, the Russian Foundation for Basic Research, Centre National de la Recherche Scientifique. It is organized within the framework of the year of FrenchRussian cooperation.
