The 12th Dialogue of the UNITE! Partnership Network took place in Espoo, Finland, from October 6th to 9th. Its main theme was "young scientists." There were also working meetings, including those related to the UNITE! Widening project, in which our department members – Professor Agata Klaus-Rosińska, Professor Dorota Kuchta, and Bartosz Stec – are greatly involved. It was also a time for establishing scientific collaborations with countries such as Spain (UPC) and France (UGA).
