This volume presents an elaborated version of lecture notes for two
advanced courses: (Re)Emerging methods in Commutative Algebra and
Representation Theory and Building Bridges Between Algebra and
Topology, held at the CRM in the spring of 2015.
Homological algebra is a rich and ubiquitous area; it is both an active
field of research and a widespread toolbox for many mathematicians.
Together, these notes introduce recent applications and interactions of
homological methods in commutative algebra, representation theory and
topology, narrowing the gap between specialists from different areas
wishing to acquaint themselves with a rapidly growing field. The covered
topics range from a fresh introduction to the growing area of support
theory for triangulated categories to the striking consequences of the
formulation in the homotopy theory of classical concepts in commutative
algebra. Moreover, they also include a higher categories view of Hall
algebras and an introduction to the use of idempotent functors in
algebra and topology.
