Combinatorial Algebraic Geometry is a subfield of algebraic geometry which studies the many families of algebraic varieties arising in commutative algebra, representation theory, mathematical physics, and other fields, which have an explicit combinatorial structure. Toric varieties and Schubert varieties are traditionally the most prominent examples. However, many other spaces, such as the moduli space of curves and the Hilbert scheme of points, lie within this conceptual framework.

Since then, this area of mathematics has seen tremendous growth in the diversity of designs, constructions, and applications that it encompasses. The purpose of this session is to showcase recent results in topics such as classical designs, cycle systems, graph decompositions, Latin squares and other aspects of design theory.

Horizons in Operator Algebras

Operator algebras studies algebras of bounded linear operators on Hilbert spaces. Originating in the late 1920s and early 1930s to provide a rigorous mathematical framework for quantum mechanics, the field has become central to modern mathematics and theoretical physics, serving as a foundation for quantum information theory and quantum computing. Work in operator algebras and noncommutative geometry has also influenced number theory, harmonic analysis, model theory, group theory, knot theory, and ergodic theory. This session aims to highlight recent advances, discuss open questions, and explore new connections in the field. This session is done in organization with Paul Skoufranis (York).

Education Sessions

Gender Equity in the Mathematical Sciences
Org: Keira Gunn (Mount Royal University), Yu-Ru Liu (University of Waterloo) and Hermie Monterde (University of Regina)
Equity, Diversity, and Inclusion (EDI) have become integral to the framework of Canadian higher education. In this session, we offer a more nuanced approach to gender equity - the act of promoting fairness, impartiality and justice amongst all people regardless of gender. We gather leading advocates in the mathematical sciences to present effective strategies for gender equity and discuss initiatives that were successful in promoting the work of people with historically underrepresented genders (including, but not limited to, women, transgender individuals, nonbinary people, gender non-traditional folks, etc). We also welcome talks about the current discourse on gender diversity and the intersectionality of gender with other aspects of one's identity (such as race, class, cultural background, etc.).

Joy in university math classes
Org: Matt Coles (University of British Columbia), Peter Harrington (Yale University) and Kelly Paton (University of British Columbia)
Fun and joyful activities are one way to entice students to come to class, keep them engaged while they are there, and help them appreciate the beauty of mathematics. In this session we want to learn from instructors who have run activities in university classes that have brought their students joy. The session will conclude with a round table discussion centered on ways to bring joy to the university math classroom and the relative importance of joy in university mathematics.

We expect this session to be dynamic and interactive, so come prepared to participate in the activities run by the presenters. Presentations will run consecutively, so while you are welcome to leave or enter the session freely, the times on the following schedule are only an estimate of when each presentation will start and end.
