Béla Szőkefalvi-Nagy (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 Lomonosov Medal in 1979: the Béla Szőkefalvi-Nagy Medal honoring his memory is awarded yearly by Bolyai Institute. == His books == * Béla Szőkefalvi-Nagy: ''Spektraldarstellung linearer Transformationen des Hilbertschen Raumes''.(German) Berlin, 1942. 80 p.; 1967. 82 p. * Frederic Riesz, Béla Szőkefalvi-Nagy: ''Leçons d'analyse fonctionnelle''.
