László Lovász

László Lovász, born on March 9, 1948 in Budapest, is a Hungarian mathematician and professor emeritus at Eötvös Loránd University, best known for his work in combinatorics, for which he was awarded the 2021 Abel Prize jointly with Avi Wigderson. He won three gold medals and one silver medal at the International Mathematical Olympiad in the 1960s, and Paul Erdős helped introduce him to graph theory at a young age. In graph theory his notable contributions include the proofs of Kneser's conjecture and the Lovász local lemma and the formulation of the Erdős-Faber-Lovász conjecture, and he is one of the authors of the LLL lattice reduction algorithm. He was president of the International Mathematical Union from 2007 to 2010 and of the Hungarian Academy of Sciences from 2014 to 2020.
