Kaisa Matomäki

from Wikipedia, the free encyclopedia

Kaisa Sofia Matomäki (born April 30, 1985 ) is a Finnish mathematician who specializes in analytical number theory.

Matomäki studied mathematics at the University of Turku with a diploma in 2005 from Matti Jutila (diploma thesis on the existence of small gaps between prime numbers). During her studies she was a trainee at the Nokia Research Center . In 2009 she received her PhD with Glyn Harman at Royal Holloway College, University of London (Applications of sieve methods in analytic number theory). She then did research again at the University of Turku, where she became a lecturer in 2014 and an Academy Research Fellow in 2015.

For 2016 she received the SASTRA Ramanujan Prize with Maksym Radziwill . The prize was awarded in particular for their joint publication Multiplicative functions in short intervals from 2016, which, after the laudation, represents a breakthrough in analytical number theory . It establishes a connection between the behavior of multiplicative number theoretic functions (such as the Möbius function and the Liouville function ) at small distances to that at large distances (where their behavior is partly well known). They used the theorem, for example, to advance the Chowla conjecture .

In 2016 she was an invited speaker at the European Congress of Mathematicians in Berlin ( Around the Möbius function , with Radziwill). In 2019 she received the New Horizons in Mathematics Prize with Radziwill . For 2020/21 she received the EMS Prize .

She is married and has three children.
