Simon and his collaborators, Chris and Erin, recently got together with Lauren Holcomb-Smith to discuss their Open Educational Resource (OER) on mathematical reasoning. The podcast is available here (https://openeducation.podcast.audio/@storiesofopenness/episodes/OER-maths/activity) as well as Apple and Spotify podcasts and the book can be found here (https://deakin.pressbooks.pub/mathematicalreasoninginvestigation/).

Lashi Bandara was invited to visit number of research centres in Europe (Germany, Sweden, United Kingdom and Portugal) from mid-December 2025 till mid-February 2026.

This week a delegation of six staff members, two PhD students and six undergraduate students from the DMG attended the AustMS meeting at Latrobe University. We gave the following talks:

• Lashi Bandara – The space of rough Riemannian metrics; Harmonic analysis and boundary trace for first-order elliptic operators over vector bundles and Cutting and gluing via matching boundary conditions.

Simon James and Julien Ugon attended the Meanjin Delta conference on the 25 and 26th of November. Julien presented a talk titled “Co-constructive mastery-based learning in mathematics” and Simon’s presentation was titled “Five years of the mathematics yearbook: a side quest in co- constructive learning”. We acknowledge funding from the faculty of SEBE that enabled us to attend this conference.
