The 9th edition of the conference "Advances in Representation Theory of Algebras" (ARTA) will be held at Queen's University in Ontario, Canada from June 12 to June 16 in 2023. The conference will feature talks and poster presentations on recent developments in the following topics:

• 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.
