Tibor Szele

Tibor Szele (born January 26, 1918 in Debrecen , † April 5, 1955 in Szeged ) was a Hungarian mathematician and university professor .

Life and career

There is only sparse information about the life of Tibor Szele. He won the Eötvös competition in 1936 and began studying engineering in Budapest , but after one semester he switched to studying mathematics and physics at the University of Debrecen . In 1941 he obtained the diploma . His dissertation , completed in 1941 under the guidance of László Rédei , only led to a doctorate at the University of Szeged in 1946 - after military service in World War II . Szele became a lecturer at the University of Debrecen in 1948 and professor in 1952 .

He died after a short, serious illness.

Scientific achievements

Tibor Szele dealt mainly with pure mathematics , especially with module and ring theory , group theory and graph theory . For the latter, he provided the solution to a problem posed by László Rédei in his dissertation and also gave a combinatorial proof of a graph-theoretical theorem by Rédei in 1943 . He proved important structural theorems in the theory of infinite Abelian groups , his central area of ​​work, and also gave a generalization of a theorem by György Hajós about finite Abelian groups. In ring theory he (together with László Fuchs ) proved an important theorem about the structure of semi-simple rings . He also gave a simple direct derivation of Zorn's lemma from the axiom of choice .

Tibor Szele is author or co-author of 62 scientific publications and author of a textbook on algebra . He is considered a pioneer of the Hungarian algebra school. Together with Alfréd Rényi and Ottó Varga , he founded the Publicationes Mathematicae Debrecen .

Honors

Tibor Szele was honored with the Kossuth Prize in 1952 . In his memory, the Bolyai János Matematikai Társulat has awarded the Tibor Szele Medal every year since 1970 .
