## Academic Year 2017/2018 - Number Theory Seminars

The Algebra and Number Theory group of the University of Luxembourg hosts three seminars.

- The
**Luxembourg Number Theory Seminar** hosts invited speakers and takes place occasionally.
- In the
**Research Seminar** the group members study a topic together; during term time the seminar takes place weekly.
- In the
**Work in Progress Seminar** the group discusses its work in progress; during term time the seminar takes place weekly.

Unless announced otherwise, the seminars take place in the "work place" in the 6th floor of
the Maison du Nombre in Esch-Belval.

Everyone is invited to attend!
For more information, please contact Gabor Wiese.
