A mathematician is a person whose primary area of study and research is the field of Mathematics. Győr (ˈɟøːr, known under alternative names) is the most important city of northwest Hungary, the capital of Győr-Moson-Sopron county and lies Hungary (Magyarország 'mɔɟɔrorsaːg) officially in English the Republic of Hungary ( Magyar Köztársaság, literally Magyar (Hungarian Republic Budapest ( also /ˈbʊ-/) is the capital city of Hungary.

The word rector ("ruler" from the Latin regere and Rector meaning "Teacher" In Latin has a number of different meanings but all of them indicate an academic The meaning of the word professor ( Latin: professor, person who professes to be an expert in some art or science teacher of highest rank) varies The University of Szeged is one of the most distinguished universities in Hungary and in Central Europe. He was the older brother of the mathematician Marcel Riesz. Marcel Riesz ( November 16, 1886 – September 4, 1969) was a Hungarian Mathematician who was born in Győr,
Riesz did some of the fundamental work in developing functional analysis and his work has had a number of important applications in physics. For functional analysis as used in psychology see the Functional analysis (psychology article His work built on ideas which had been introduced by Fréchet, Lebesgue, Hilbert and others. Maurice Fréchet ( September 2, 1878 – June 4, 1973) was a French Mathematician. Henri Léon Lebesgue leɔ̃ ləˈbɛg ( June 28, 1875, Beauvais &ndash July 26, 1941, Paris) was a French David Hilbert ( January 23, 1862 &ndash February 14, 1943) was a German Mathematician, recognized as one of the most He also made many contributions to other areas including ergodic theory and he gave an elementary proof of the mean ergodic theorem. Ergodic theory is a branch of Mathematics that studies Dynamical systems with an Invariant measure and related problems

- F. There are several well-known theorems in Functional analysis known as the Riesz representation theorem. In Mathematics, the F and M Riesz theorem is a result of the brothers Frigyes Riesz and Marcel Riesz, on analytic measures.
