Tsuyoshi Ando achieved
significant, deep results in a wide range of mathematics, including
measure theory, ordered Banach spaces, operator theory and matrix
analysis. He has contributed ten definitive research papers to the Acta Scientiarium Mathematicarum. His celebrated
theorem on the existence of unitary dilations of pairs of commuting
contractions was also published here 42 years ago.

The Béla Szőkefalvi-Nagy medal founded in memory of Béla Szőkefalvi-Nagy, who served as
Editor-in-chief of the Acta Scientiarium Mathematicarum from 1946 to
1981. The Medal is awarded annually by the Bolyai Institute to honour a
distinguished mathematician who has published significant, deep results
in these Acta.
