Collected Papers

Marcel Riesz (1886-1969) was the younger of the famed pair of mathematicians and brothers. Although Hungarian he spent most of his professional life in Sweden. He worked on summability theory, analytic functions, the moment problem, harmonic and functional analysis, potential theory and the wave equation. The depth of his research and the clarity of his writing place his work on the same level as that of his brother Frederic Riesz. This edition of his Collected Papers contains most of Marcel Riesz's published papers with the exception of a few papers in Hungarian that were subsumed into later books. It also includes a translation by J. Horvath of Riesz's thesis on summable trigonometric series and summable power series. They are thus a valuable reference work for libraries and for researchers.

Marcel Riesz (16 November 1886 – 4 September 1969) was a Hungarian-born mathematician, known for work on summation methods, potential theory, and other parts of analysis, as well as number theory, partial differential equations, and Clifford algebras. He spent most of his career in Lund (Sweden). He was born in Gyor, Hungary (Austria-Hungary); he was the younger brother of the mathematician Frigyes Riesz. He obtained his PhD at Eotvos Lorand University under the supervision of Lipot Fejer. In 1911, he moved to Sweden upon the invitation of Gosta Mittag-Leffler. From 1911 to 1925 he taught at Stockholms hogskola (now Stockholm University). From 1926 to 1952 he was professor at Lund University. After retiring, he spent 10 years at universities in the United States. He returned to Lund in 1962, and died there in 1969. Riesz was elected a member of the Royal Swedish Academy of Sciences in 1936.
