Numbers, Functions, Equations ’98
(May 31 – June 6, 1998, Noszvaj, Hungary)
The Institute of Mathematics and Informatics of Kossuth Lajos University
in Debrecen and the Institute of Informatics of Eötvös Loránd University
in Budapest organized an International Conference on Numbers, Functions,
Equations ’98 dedicated to the 60th birthday of Professors Zoltán Daróczy
(Kossuth Lajos University, Debrecen) and Imre Kátai (Eötvös Loránd University,
Budapest).
The conference was held in the De La Motte Castle in Noszvaj, Hungary
from Sunday, May 31 to Saturday, June 6, 1998. The organizing committee
was as follows:
Honorary Chairman: Prof. Dr. Dr.h.c.mult. Karl-Heinz Indlekofer (Universität
GH Paderborn, Germany).
Co-chairman: Prof. Dr. Zsolt Páles (Kossuth Lajos University, Debrecen)
and Prof. Dr. Ferenc Schipp (Eötvös Loránd University, Budapest).
Chairman of the Scientific Board: Prof. Dr. László Székelyhidi (Kossuth Lajos
University, Debrecen).
Members of the Scientific Board: Prof. Dr. János Fehér (Janus Pannonius
University, Pécs), Prof. Dr. Károly Lajkó (Kossuth Lajos University, Deberecen),
and Prof. Dr. László Lakatos (Eötvös Loránd University, Budapest).
Secretaries: Dr. Zoltán Boros and Dr. Attila Gilányi (Kossuth Lajos University,
Debrecen).
Technical Organizers: Prof. Dr. Árpád Száz, Prof. Dr. Sándor Kántor, Gabriella
Hajdu and Tibor Farkas (Kossuth Lajos University, Debrecen).
Mathematicians from 15 countries participated in the conference. From
abroad, Poland contributed the largest number, with 10 participants. This
is due not only to the Polish-Hungarian friendship but especially to the close
cooperation between the schools of functional equations in the two countries.
Here, the role of Professor János Aczél, who was the father of this school
in Debrecen, and Professor Zoltán Daróczy’s strength and determination in
keeping the very successful working connections between the Canadian and
Hungarian schools alive during the hard political times have to be mentioned.
For many years, there has been intensive and fruitful cooperation between
Hungarian, German and Lithuanian mathematicians in different areas
of number theory under the scientific supervision of Imre Kátai. Due to
these cooperations, we had 6 mathematicians from Germany and 5 from
Lithuania.
Furthermore, there were 4 participants from the USA, 3 from Rumania,
2 from France, 1 each from Austria, the Netherlands, Italy, Russia, Ukraine,
Spain and Yugoslavia, and 39 from Hungary.
The lectures covered a variety of topics. Mainly connected to the research
areas of the celebrated professors, they dealt with the theory of functional
equations and number theory. There were presentations about the solution of
special functional equations, the smoothness of solutions, and the stability of
means and functional equations. In number theory, there were talks about
