thought we’d need an entry homotopy category of chain complexes
I have expanded homotopy category of chain complexes by adding a few basics.
In the course of this I have also touched the formatting of the following entries:
triangulated category (and all the related, such as enhanced dg-category)
Will be further working on derived category now.
I needed to spell out somewhere a very basic expositional example of what goes wrong in $\mathcal{K}(\mathcal{A})$ that is rectified in the derived category such that the example roughly motivates the idea of projective resolutions. I ended up putting it here into a new section Examples - Chain homotopies that ought to exist but do not. It could probably go elsewhere just as well.
