Algebraic Combinatorics (IM2)
Organizer and Chair: Steph Van Willigenburg (University of British Columbia)

Analytic Combinatorics (IM3)
Organizer and Chair: Alfredo Viola (Universidad de la República, Uruguay)
As defined in the book ``Analytic Combinatorics'' by Philippe Flajolet and Robert Sedgewick (2009): "Analytic combinatorics aims to enable precise quantitative predictions of the properties of large combinatorial structures. The theory has emerged over recent decades as essential both for the analysis of algorithms and for the study of scientific models in many disciplines, including probability theory, statistical physics, computational biology and information theory". This minisymposium aims at presenting new results and applications in the area.

Combinatorics and Geometry of Linear Optimization (IM4)
Organizer and Chair: Antoine Deza (McMaster University)
Optimization has long been a source of inspiration and applications for geometers, and similarly, discrete and convex geometry have provided foundations for many efficient optimization techniques. Combinatorics forms an intrinsic part of optimization, and there is a rich interplay between geometry and combinatorics. The intent of the minisymposium is to bring together geometers and combinatorial and continuous optimizers.
