| Org: Susanna Dann (Universidad de los Andes, Bogota, Colombia), Daniel Galicer (Universidad de Buenos Aires , Argentina) et Alexander Litvak (University of Alberta) | |
| Asymptotic Geometric Analysis (AGA) is mainly concerned with geometric and linear properties of infinite dimensional objects, such as convex sets and normed spaces, especially with the characteristic behavior that emerges when the dimension, or a number of other relevant free parameters, is suitably large or tends to infinity. High-dimensional systems are very frequent in mathematics and applied sciences hence understanding of high-dimensional phenomena is becoming increasingly important. By virtue of AGA general framework, methods, and its impact on related fields, AGA can be situated at the crossroads of many branches of mathematics: functional analysis, convex and discrete geometry (described below), several areas of probability including random matrix theory, some aspects of graph theory, among others. | |

All this is further enhanced by methods from combinatorics. This scientific session is intended to be a meeting place for senior and junior experts of discrete geometry, convexity, and combinatorics in order to interact and share their ideas about current problems, recent advances and emerging directions. | |

Students need to be thinking about these issues throughout their education, so they can use mathematics ethically and responsibly.

| Org: Egan Chernoff (University of Saskatchewan) et Rina Zazkis (Simon Fraser University) | |
| As the field of mathematics education continues to expand and evolve, an argument has been made that mathematics is getting left behind in mathematics education. Trending research topics, for example, mathematics anxiety, social justice, classroom technology, pedagogical trends, assessment and evaluation, and many others, while important, are also beginning to eclipse mathematics education research that leans heavily on mathematics. However, a dedicated group of Canadian researchers continues to embrace the mathematics of mathematics education, that is, they further the focus on the teaching, learning and understanding (or understanding better what was understood previously) of various mathematical topics and ideas. Said work will be highlighted and explored in this Education Session of the 2024 Winter Meeting of the Canadian Mathematical Society . Please join us. | |
