NATO Advanced Study Institute

New Challenges in Digital Communications
April 28 -- May 9, 2008
Vlora, Albania

Scientific programme

The goal of this summer institute is to discuss the new challenges in  communication theory from a mathematical viewpoint. The lectures will be  focused on 3 main directions:
  • Computational algebra and communication theory
  • New trends in coding theory
  • Computer security and cryptography
We intend to provide the mathematical background and tools for young  researchers who want to enter these exciting areas.

Proceedings Volume

Developments of the last few decades in digital communications have created a close link between mathematics and areas of computer science and electrical engineering. A collaboration between such areas now seems very natural, due to problems which require deep knowledge and expertise in each area. Algebra and some of its branches, such as algebraic geometry, computational algebra, group theory, etc., have played a special role in such collaboration. As a result, there are now disciplines such as coding theory and cryptography, which are considered a mix of mathematics, computer science and electrical engineering. Algebraic Aspects of Digital Communications focuses on connections between algebra, algebraic geometry, number theory, graph theory and related areas of mathematics with coding theory and cryptography. This publication is aimed at mathematicians, computer scientists and engineers who need to explore ties between algebra and coding theory and cryptography.

IOS Press is an international science, technical and medical publisher of high-quality books for academics, scientists, and professionals in all fields.

Visa requirements:

Dealing with Albanian authorities can be frustrating and time consuming. All participants from North America  and European Union do not need visas to visit Albania. However, people from other countries might need  visas. The conference organizers will send a formal invitation for visa purposes to everybody who will need a  visa. However, we are not responsible for helping with visa issues. Please visit the website of the Ministry of  Foreign Affairs of Albania to find information how to apply for a visa.
