| Analytic–Geometric Synergies: Harmonic Analysis and Convexity | |
| Org: Almaz Butaev (University of the Fraser Valley), Galia Dafni (Concordia University) and Serhii Myroshnychenko (University of the Fraser Valley) | |
| Harmonic analysis and convex geometry are two areas of mathematics with deep historical connections and a growing number of modern interactions. Techniques from Fourier analysis have proven to be indispensable in addressing fundamental problems in convex and discrete geometry, such as volume inequalities, characterizations of special convex bodies, and stability questions. Conversely, geometric insights often inspire new analytic methods and results. | |
| Combinatorial Algebraic Geometry | |
| Org: Megumi Harada, Brett Nasserden and Alexandre Zotine (McMaster University) | |
| 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. | |
| Combinatorial Design Theory | |
| Org: Alice Lacaze-Masmonteil (University of Regina), David Pike (Memorial University of Newfoundland) and Doug Stinson (University of Waterloo) | |
| In the 18th century, several seemingly innocuous scheduling problems were proposed, often in the form of a puzzle. These problems were ultimately solved using tools and theoretical approaches that now lie in what is known as combinatorial design theory. 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. | |
