| Org: Masoomeh Akbari (University of Ottawa), Kianoosh Shokri (University of Ottawa) and Brett Stevens (Carleton University) | |
| Combinatorial design theory studies the existence, construction, and structure of arrangements of finite objects, such as subsets, arrays, and graphs, that satisfy prescribed constraints. Leonhard Euler studied pairs of orthogonal Latin squares in the 18th century, with design theory's origins tracing back even earlier to a magic square on a turtle’s back in ancient China around 2200 BC. In the 20th century, connections with statistics, algebra, and finite geometry, together with the development of computational methods, opened new directions in the field. Today, combinatorial design theory is a multidisciplinary area with applications in algorithm design, cryptography, wireless communication, and coding theory, and has seen significant recent growth. The purpose of this session is to showcase recent results on classical designs, cycle systems, graph decompositions, Latin squares, and related topics. | |

| Org: Beth Ann Austin (Memorial University), Iain Beaton (Acadia University) and Danielle Cox (Mount Saint Vincent University) | |
| Many problems in graph searching include searcher(s) trying to capture a mobile evader in a network. There is a rich history of variant problems which explore different actions of searchers and robbers, conditions of capture, speed, or visibility. Recently, there have been more developments in the field of graph searching, especially when it comes to deterministic and probabilistic problems. This session aims to draw on the research of people working on a variety of graph searching problems such as cops and robbers, localization, firefighting, graph burning, and eternal domination. | |

One approach to finding efficient algorithms is to study the structure of graphs which are restricted in various ways. This session will focus on graph structure and its application to designing efficient algorithms for important problems including graph colouring, homomorphisms, combinatorial reconfiguration, flows, packings and coverings, and finding Hamiltonian cycles. | |

Education Sessions
| Mathematics for Play, Community, and Connection: A Public Recreational Math Expo | |
| Org: Hope Alderson (University of New Brunswick (Saint John)) and John Grant McLoughlin (University of New Brunswick (Fredericton)) | |
| A public Recreational Mathematics Expo is being held alongside the 2026 CMS Summer Meeting in Saint John. The event welcomes families, teachers, students, and community members to engage with mathematics through hands-on activities, puzzles, and games, highlighting mathematics as playful, creative, and accessible. The Expo will foster community engagement and outreach while complementing the research and education sessions of the CMS meeting. | |
| Teaching and learning of university mathematics: how have things evolved (or not)? | |
| Org: Andrijana Burazin (University of Toronto, Mississauga) | |
| Studying how university mathematics teaching and learning have evolved is challenging due to time, financial, and logistical constraints, as well as diverse student populations and rapidly changing contexts. This education session brings together a diverse set of university instructors at different career stages to reflect and provide examples on shifts in teaching practices, student attitudes, assessment design, supervision, and the role of technology, including generative AI. By sharing real-time experiences, presenters will explore what has meaningfully changed, what has remained the same, and what actions (if any) are needed moving forward. | |
