Meetings/Workshops on Algebra in Canada

The Fields Institute

The purpose of the workshop is to accelerate the development of this emerging subject and to extend its applications to other areas, in particular to group theory, geometry and combinatorics.

The modern approaches to computing algebraic K-groups step through equivariant commutative ring spectra via the natural S1-action on topological Hochschild homology. Ongoing and transformative work by Bhatt--Morrow-Scholze in p-adic Hodge theory uses cyclotomic spectra and therefore subtle equivariant information. This workshop, at the vanguard of work in this area, seeks to bring together experts in algebraic topology, (derived) algebraic geometry, and number theory to explore these exciting new connections.

This is a 5-day workshop to be held at UQAM in Montreal, focusing on special geometric structures in Riemannian geometry.

The eighth edition of ARTA will present recent research developments in tilting and \tau-tilting theory, torsion theory, combinatorial methods in representation theory, geometric representation theory, module categories and self-injective algebras, homological methods in representation theory, triangulated categories, derived categories and relationship with cluster algebras. We will also explore the deep links with other closely related areas such as Lie theory and geometry, as well as possibly new research directions that would appear between now and the conference.

Banff International Research Station

The Banff International Research Station will host the "Interactions of gauge theory with contact and symplectic topology in dimensions 3 and 4" workshop in Banff from June 7 to June 12, 2020. This workshop will highlight new results in low-dimensional topology coming from a wide range of geometric methods. Low-dimensional topology studies the global properties of geometric spaces in dimensions 3 and 4, such as 3-dimensional space and 4-dimensional space-time.

Structure of finite dimensional algebras Structure of module categories Auslander--Reiten components Homological methods in representation theory Homological conjectures Algebras of finite global dimension Self-injective algebras Tame algebras Combinatorial aspects of representation theory Geometry of algebras and modules Homological invariants of algebras and modules Triangulated categories and tilting theory Relations of the above topics with Lie theory, Singularity theory, Cohen--Macaulay modules, quantum groups and other algebraic structures.

This will be a twinnd conference held simultaneously at Perimeter Institute in Waterloo, Canada and Max Planck Institute in Bonn, Germany. The two venues will be connected by live video streams, during both the talks themselves as well as informal discussion sessions. The concept of the twinned conference is motivated by the desire to reduce environmental impact of conference travels. Our hope is that this initiative will help reduce transatlantic flights, while still promoting long distance interactions.

An equation is called Diophantine if whole number or fractional solutions are sought. Diophantine equations are named after Diophantus of Alexandria, a 3rd century mathematician and were popularized by Pierre de Fermat, a 17th century lawyer and amateur mathematician. Unlike most branches of mathematics, many Diophantine questions and theorems can be understood and appreciated by the general public, and the subject is a favourite with popularizers of mathematics. The methods for tackling Diophantine equations are however deep and varied, and the subject has recently experienced an explosion of new directions and results. This workshop will bring together experts and young scholars to explore these new directions and stimulate further research into Diophantine problems.
