Seminar on stable homotopy theory (Fall 2024)
The goal of this seminar is to introduce the notion of spectra and study its basic properties. We will discuss equivalence between spectra and generalized cohomology theories, the smash product of spectra, Spanier–Whitehead duality, Atiyah duality, the Steenrod algebra, the Atiyah–Hirzebruch and Adams spectral sequences, and the relationship between stable homotopy and bordism of smooth manifolds.
This seminar is intended for graduate student. The participants are encouraged to prepare and give a talk.

Talk List & Abstract
Talk 1
- Title : Spectra : definition and examples (note)
- Abstract : In this talk, we will define spectra and Omega spectra and explain how generalized cohomology theories gives rise to Omega spectra via Brown representability. We will discuss some examples of spectra and its basic properties.
Talk 2
- Title : The homotopy category of spectra
- Abstract : In this talk, we will define the homotopy category of spectra and discuss its stability properties. We will prove that suspension induces a self-equivalence of the stable homotopy category. We will define (co)fiber sequence of spectra and construct the associated long exact sequences. We will explain how the stable homotopy category forms a triangulated category.
