I created a new, different
world out of nothing.
(János Bolyai)

The aim of the conference is to connect researchers from different countries and different fields of Mathematics and Informatics in a pleasant place of a young and growing university. The topics of the conference include all fields of Mathematics and Informatics.

The MathInfo 2017 conference will be held at the Department of Mathematics and Informatics in Târgu Mureş/Marosvásárhely, Romania, Sapientia Hungarian University of Transylvania, September 7-9, 2017.
This conference is organized every two years in the same place, the city where the famous Hungarian mathematician János Bolyai has spent most of his life.

Papers presented at the conference can be submitted for publication in our journal Acta Universitatis Sapientiae Mathematica or Acta Universitatis Sapientiae Informatica.
