Scientific Program

Program Announcement

The program of the Congress will include talks, workshops, mini-courses, problem posing sessions, plenary talks, and other events. Much of the Congress’ work will center on the following four themes:

  • Building Bridges between Problems of Mathematical Research and Competitions (chaired by Alexander Soifer);
  • Creating Problems and Problem Solving (chaired by Krzysztof Ciesielski);
  • Competitions around the World (chaired by Maria Losada);
  • Technological Applications in Mathematics Competitions (chaired by Lukas Donner).

Participants are invited to submit proposals for talks, workshops, mini-courses, posters and other mathematical content. These should include titles, the names of authors or organizers, and clear concise descriptions.
