The event is the ninth in a series started in 2015. The symposium has grown from a one-day format with around 20 participants to a three-day meeting with around 100 participants. Over the years, it has also become a meeting place for young European number theorists, fostering collaboration and exchange within this vibrant community. This year's symposium holds special significance as it is dedicated to celebrating the 80th birthday of Michel Waldschmidt, whose lifelong contributions to number theory and the global mathematical community are deeply inspiring.
