Béla Andrásfai (8 February 1931 – 6 June 2023) was a Hungarian mathematician. The Andrásfai graph was named after him.
Andrásfai began his high school studies in 1942 at Verbőczy High School in Budapest, continued at Szombathely High School in 1946, and graduated from high school in 1951. In 1954 he graduated as a teacher of mathematics and physics from the Budapest College of Pedagogy, and in 1957 from Eötvös Loránd University. Between 1953 and 1955 he was a teaching assistant at the Department of Mathematics at the College of Pedagogy, then went on to the Faculty of Electrical Engineering of the Budapest Technical University. Assistant professor from 1963, associated professor from 1965 until his retirement in 1996. In 1963 he was awarded the title of Candidate of Mathematical Sciences. Designer and subject lecturer of the course Discrete Mathematics. At the invitation of the Mathematical Institute of the Eötvös Loránd University, he taught the Mathematics on the Dock as an optional course in the spring semester of 2011.
His public life was also significant. He held various positions at the János Bolyai Mathematical Society, organized conferences, and gave numerous lectures to primary and secondary school teachers.
His scientific work was in the field of graph theory. The extreme graphs he described and investigated are called Andrásfai graphs, which were later generalized.[1] Author of several scientific articles, professional books, university notes.[2]
Andrásfai died in Budapest on 6 June 2023, at the age of 92.[3]
