Prerequisites: We assume basic knowledge of topology as taught in Topology I and II.
Content: The seminar will cover advanced topics from topology and homotopy theory.
The study of group actions is ubiquitous in mathematics as historically groups arose from the study of symmetries. The study of continuous group actions on topological spaces is therefore fundamental to many areas of mathematics. Stable equivariant homotopy theory provides a world for studying duality in the setting of spaces with a continuous action of a group, such as Spanier-Whitehead duality. Equivariant stable homotopy theory has a long rich history and it remains an active area of research. In part, this is because it has lead to resolutions of open problems in other areas of topology, which on the face of them, do not seem related to equivariant stable homotopy theory at all.
This seminar will begin with some non-equivariant stable homotopy theory and equivariant unstable homotopy theory. We will then learn the fundamental constructions in equivariant stable homotopy theory and carefully prove some of the fundamental results in the subject.
