10th International Mathematics and Informatics Conference

Distance and critical points


September 8-12, 2025

Târgu Mureş/Marosvásárhely, Romania

Motto:
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.

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.

The topics of this years conference is related to optimizing any kind of distance on algebraic varieties, manifolds, polytopes, etc. Topics will include, but will not be restricted to, the study of algebraic and topological properties of the singularities of the related distance functions, the study of their discriminants, etc.

Besides the invited plenary talks, the registered participants will have the possibility to submit contributed talks, additionally Ph.D. students will have the possibility to submit posters. There will be free accommodation for several Ph.D. students based on a preselection. On Wednesday there will be an excursion organized to visit the town of Sighișoara, which is a popular tourist destination for its well-preserved old town, being listed by UNESCO as a World Heritage Site. In that evening there will be a festive dinner, including a wine tasting at the nearby Castel Haller.
