Norway’s Crown Prince Haakon addresses media after Abel Prize ceremony

Crown Prince Haakon of Norway faced the press outside the University of Oslo on Tuesday following the award ceremony for the 2026 Abel Prize, Dagbladet reports.

The encounter comes days after reports that his son, Prince Sverre Magnus, 20, has returned to Norway after living in Italy, where he had launched a production company in Milan. The crown prince has not publicly commented on the move or on the health of his mother, Queen Sonja, who cancelled a regional tour this week due to a heart condition.

Queen Sonja, 88, remains on medical leave for one week after being diagnosed with atrial fibrillation and heart failure, according to a statement from the Royal Court on Monday. While described as in “good spirits,” she requires rest and medication adjustments.

Meanwhile, Crown Princess Mette-Marit continues to scale back official duties due to chronic pulmonary fibrosis. Earlier on Tuesday, it was announced she would not attend the annual Skaugum Estate football match, where she typically serves as team leader for Team Skaugum. Crown Prince Haakon and Prince Sverre Magnus will instead represent the team in her absence.

The Abel Prize, awarded by the Norwegian Academy of Science and Letters on behalf of the Ministry of Education, was presented to German mathematician Gerd Faltings of the Max Planck Institute for Mathematics. Faltings received the 7.5 million NOK prize for “introducing powerful tools in arithmetic geometry and solving long-standing Diophantine conjectures by Mordell and Lang,” according to the academy.

The prize ceremony marks the start of Abel Week, a series of lectures and academic events in Oslo gathering mathematicians from around the world.
