This LUMAT special issue is a collection of selected papers from the 24^th international conference of mathematical views that was held on August 20–22, 2018 in Helsinki, Finland. The conference was a wonderful opportunity to elaborate issues related to mathematics-related affect among colleagues interested in this area of research. Out of the 25 conference presentations, 12 were submitted as a manuscript for peer review. After the review and revisions, we ended up with eight articles that you can read in this special issue.
