The forth part of the course on algebraic topology gives a systematic study of cohomology theories via the so-called spectra.
The spectra in algebraic topology are a basic tool in homotopy theory.
The short description is: spectra are a generalization of topological spaces, where the suspension construction has an inverse:
every spectrum is a suspension of some other spectrum (at least upto homotopy equivalence). As a consequence, spectra often
have homotopy groups in negative degrees.
It turns out that to every spectrum one can associated a generalized (co)homology theory, and that, on the other hand, every
such is represented by a spectrum. Transformations of generalized cohomology theories correpond to maps of spectra.
In the course we will
- introduce the category of spectra (objects and maps), -construct the associated (co)homology theory,
- learn about the structure theory (e.g. fibration and cofibrations of spectra, assoziated decomposition of cohomology theories)
- describe some of the most important examples: sphere spectrum, Eilenberg-MacLane spectra, Thom spectra corresponding to
bordism theories, K-theory spectrum.
homology and cohomology, homotopy groups, fibrations. Not required: knowledge
of spectral sequences.
