and named for the Finnish mathematician Rolf Nevanlinna. It consists of a gold medal and cash prize. The prize is targeted at younger theoretical computer scientists, and only those younger than 40 on January 1 of the award year are eligible. It is awarded along with other IMU prizes including the Fields Medal.
Naming

The prize was originally named to honour the Finnish mathematician Rolf Nevanlinna who had died a year before the prize's creation in 1981. The medal featured a profile of Nevanlinna, the text "Rolf Nevanlinna Prize", and very small characters "RH 83" on its obverse. RH refers to Raimo Heino, the medal's designer, and 83 to the year of first minting. On the reverse, two figures related to theUniversity of Helsinki

Alexander Soifer, president of the World Federation of National Mathematics Competitions, complained about the prize's honouring of Nevanlinna, as he was a supporter of Hitler and had acted as a representative for the Finnish Volunteer Battalion of the Waffen-SS during World War II. Soifer discussed Nevanlinna's wartime activities in a 2015 book, and forwarded his personal and his organization’s requests to the Executive Committee of IMU to change the Prize's name. In July 2018, the 18th General Assembly of the IMU decided to remove the name of Rolf Nevanlinna from the prize. It was later announced that the prize would be named the IMU Abacus Medal.
