It was a great pleasure to welcome you all to the 31st International Conference on Mathematical Views (MAVI 31), hosted by Linnaeus University in Växjö, Sweden, from 17 to 19 September 2025. Over more than three decades, the MAVI conference was establishedas a distinctive and influential forum for research on affectiveand value-related dimensions of mathematics education. MAVI 31 continuedthis tradition by bringing together a diverse international community of scholars, 43 participants from 14 different countries and 32 contributions,at a time when such perspectives are more necessary than ever.Of the 32 contributions, 24 are represented as peer-reviewed papers in the conference proceedings. This proceeding also contains a contribution by Prof. Dr Günter Törner, in which he looks back on the MAVI community and its developmen.
