Symposium on Number Theory and its Applications
In Honor of Olivier Ramaré's 60th Birthday
May 22-23, 2025

The Symposium on Number Theory and its Applications will be held at the Johann Radon Institute for Computational and Applied Mathematics (RICAM) of the Austrian Academy of Sciences from May 22 to May 23, 2025.

Description

In 1742, the mathematician Christian Goldbach wrote a letter to Leonhard Euler in which he proposed the following conjecture: every even natural number greater than 2 can be expressed as the sum of two prime numbers. This famous conjecture, known as Goldbach's Conjecture, remains one of the oldest and most well-known unsolved problems in number theory, and maybe even in mathematics.

In 1995, Olivier Ramaré made a significant breakthrough by proving that every even number can be written as the sum of at most six prime numbers. This result, closely related to Goldbach's Conjecture, reinvigorated research in the field and inspired further studies on additive number theory.

Over the past 30 years of his remarkable research career, Olivier Ramaré has made numerous profound contributions to number theory. His work spans a wide range of topics, including the large sieve inequality, the Brun-Titchmarsh theorem, primes in arithmetic progressions, the Möbius function, and many more.

This symposium celebrates Olivier Ramaré's outstanding contributions to number theory and provides a platform for Ramaré's colleagues and friends to discuss recent advances in the field. We welcome mathematicians from around the world to join us in honoring his achievements and exploring new directions in number theory and its applications.
