An international conference on number theory greeted the 75 year-old Kalman Győry, Szechenyi Prize-winning mathematician and former rector of the University of Debrecen.
- I am very proud that I can work at a university with
Kálmán Győry. We can look up to him not only professionally, but also in human terms, and his personality and way of thinking have had a huge impact on all of us and still do - said
Zoltán Szilvássy, Rector of the University of Debrecen in his speech at Friday's opening ceremony of the conference organized to commemorate the 75th birthday of Kálmán Győry.
The two-day scientific meeting entitled 75 Győry featured lectures by thirteen academics with links to Kálmán Győry’s work.
Ákos Pintér, the Dean of the Faculty of Science and Technology introduced the career of the former rector of Debrecen University in a lecture entitled "Győry 75 : an outstanding scientific career".
The Szechenyi Prize-winning mathematician was born in 1940 in Ózd, and in 1964 graduated from the University of Lajos Kossuth Science Mathematics Department. Pál Turán introduced him to the world of Diophantine number theory and between 1962 and 1976 acted as his mentor. During his career Kálmán Győry solved several old mathematical problems and demonstrated several theories as well as authoring about 180 publications. As a leader, he has also achieved much for the university and for mathematics in Debrecen: between 1988 and 2005 he was head of the Department of Algebra and Number Theory, between 1993 and 1998 dean of the Faculty of Science and from 2001 to 2002 rector of the University. In addition to his scientific work his efforts to build academic schools is also significant: he is the founder of the university's Number Theory Research Group and his students include an academician and five academic doctors.
Endré Szemerédi has enjoyed a 50-year friendship with Kalman Győry and they speak frequently, and not only about mathematical and specialist questions. According to the Abel Prize-winning mathematician, the Number Theory Research Group, founded by Győry Kalman in Debrecen, is a unique creation.
- Every second or third year, a serious researcher emerges from among his former students, he has created an exceptional school, and despite his 75 years, he still has the energy to continue his work - stressed Endre Szemerédi.
The Abel Prize-winning mathematician also gave a lecture at the conference, entitled "Maximum size of a set of integers with no two adding up to a square", exploring an answer to the question of what size of set is necessary to ensure certain equations are solvable with the elements in the set.
