Béla Szőkefalvi-Nagy

Béla Szőkefalvi-Nagy [beːlɒ søːkɛfɒlvi nɒɟ] (29 July 1913, Kolozsvár – 21 December 1998, Szeged) was a Hungarian mathematician. His father, Gyula Szőkefalvi-Nagy was also a famed mathematician. Szőkefalvi-Nagy collaborated with Alfréd Haar and Frigyes Riesz, founders of the Szegedian school of mathematics. He contributed to the theory of Fourier series and approximation theory. His most important achievements were made in functional analysis, especially, in the theory of Hilbert space operators. He was editor-in-chief of the Zentralblatt für Mathematik, the Acta Scientiarum Mathematicarum, and the Analysis Mathematica. He was awarded the Kossuth Prize in 1953, along with his co-author F. Riesz, for his book Leçons d'analyse fonctionnelle.[1] He was awarded the Lomonosov Medal in 1979. The Béla Szőkefalvi-Nagy Medal honoring his memory is awarded yearly by Bolyai Institute.

Award in his honour Edit

In 1999, Béla Szőkefalvi-Nagy's daughter Erzsébet, established the Béla Szőkefalvi-Nagy Medal to remember her father. This medal is meant to recognize distinguished mathematicians who have published significant work in Acta Scientiarum Mathematicarum. The following mathematicians have been awarded the medal:[2]
