Jenő Szép

His parents were Pál Szép and Arabella Liebert. His wife's name was Gabriella Tésy. He graduated from the Miklós Zrínyi Real High School in Budapest in 1938, obtained a teacher's diploma in mathematics and physics at the Pázmány Péter University in 1943, as well as a doctorate in humanities in 1946. He was awarded the degree of Candidate of Mathematical Sciences in 1952 for his advanced activities. He received his degree of Doctor of Mathematical Sciences from the Hungarian Academy of Sciences in 1957. He was an intern (1941–1943) and assistant professor (1943–1946) at the Pázmány Péter University Institute of Mathematics, alongside Lipót Fejér and Béla Kerékjártó. The Budapest Civic School Teacher Training College r. teacher (1946–1949), Szeged Pedagogical College, resp. a Szeged Teacher Training College Department of Mathematics r. teacher (1949–1952), college teacher (1952–1961) and head of the Department (1949–1961). Marx University of Economics (MKKE) Professor of the Department of Mathematics (August 10, 1961 - December 31, 1992) and Head of the Department (1961–1976), also Director of the Institute of Mathematics and Computer Science (1976-87).

Even before his arrival, it was completed in 1960 - primarily Béla Krekó the curriculum of the plan-(economic) mathematics program and the later elite program. The leading individual in the introduction and maintenance of the curriculum Béla Krekó, Jenő Szép jointly. Jenő Szép achieved building and managed a team, which conducted scientific research and education not only in pure mathematics, but in the promising new methods too and gained experience in a wide range of applications. Beyond several series of textbooks, they issued a series - named Department of Mathematics, Karl Marx University of Economics - of research papers (cca. 100) in English between 1969 and 1988. He was the editor of a series of mathematical handbooks for economists in Hungarian. Professor Emeritus of the BKE (since 1995) and the Gyula Juhász Teacher Training College. Master of Emeritus (since 1995).

As a mathematician, his main research interests were algebraic structures and group theory. He is one of the authors of Zappa–Szép product, beyond papers, he published with co-authors the book titled Semigroups in 1991. As a professor of an economics university, his main interest was in game theory and dealt with many applications of mathematical methods in economics. He was the founding editor-in-chief of the international mathematical journal „ Pure Mathematics and Applications (PUMA)” in 1990 and worked on it until he died in 2004.

Since 2000, he edited seven books from the Advances in Mathematics series from Kluwer Academic Publishers until his death.

Jenő Szép has invited professors in Italian and Canadian universities for joint research and teaching courses (Róma (1961–62), Firenze (1968, 1972), Padova (1968–69), London (Kanada 1987), Lecce (1988–89), Siena (1990–2002) for several months in each case.

The list of his works has about 180 items, the Mathematical Reviews referred to 95 of his papers/books.

• „The National Memorial and Commemorative Committee decided by its decision No. 42/2022 to declare the resting place of Jenő Szép, mathematician, economist, part of the national cemetery in category "B" (Budapest, Farkasréti cemetery, 11/1-1-80)." The inclusion in the National Graveyard is an expression of the Hungarian nation's appreciation, respect and gratitude to the person buried in the grave, and also provides legal protection that prevents the grave from being dismantled.[7]
