In honour of Professors Kálmán Győry, János Pintz and András Sárközy the Institute of Mathematics of the University of Debrecen is organizing an international conference during the period July 4-8, 2022.

We do not forsee the future, but we do hope that after postponing the Conference twice, we shall be able to hold it this time. We would like to emphasize that we shall follow all the national and international regulations concerning the epidemic, and we ask our participants to be vaccinated and to have some certificate about it.
