INFOMATMars 2018 ROBERT P. LANGLANDS ER ÅRETS ABELPRISVINNER Robert P. Langlands, Institute of Advanced Study, Princeton, USA, er tildelt Abelprisen for 2018 for “sitt visjonære program som knytter sammen representasjonsteori og tallteori”. INFOMAT kommer ut med 11 nummer i året og gis ut av Norsk Matematisk Forening. Deadline for neste utgave er alltid den 15. i neste måned. Stoff til INFOMAT sendes til arnebs at math.uio.no Foreningen har hjemmeside http://www.matematikkforeningen.no/ Ansvarlig redaktør er Arne B. Sletsjøe, Universitetet i Oslo.
