27th Nordic Congress of Mathematicians - Number Theory session

This Congress is of special significance, since it will celebrate the 100th anniversary of Institut Mittag-Leffler. The Institute was founded on the 16th of March 1916 by Professor Gösta Mittag-Leffler and his wife Signe, who donated their magnificent villa with its first-class library, for the purpose of creating the Institute that bears their name. It is the oldest Mathematics Research Institute in the world. Besides running scientific programmes and conferences the Institute is responsible for publishing two research journals, Acta Mathematica and Arkiv för Matematik. Acta Mathematica was founded by Gösta Mittag-Leffler in 1882 and is one of the most prestigious mathematics research journals in the world.

The number theory session will take place March 17-19, in room 3733 at the department of mathematics at KTH. (The address is Lindstedsvägen 25, directions can be found here.)

The main page of the congress has information about registration and accomodation. If you are planning to attend the session, please register (there is no fee.)

Organizing Committee

The main congress page has some hotel recommendations. (Elite Hotel Arcadia is quite close to KTH and the subway stop that can be used to go to Stockholm University. Best Western is a bit farther away, but still walkable to KTH and the subway stop.)
