created Cisinski model structure
I have added to Cisinski model structure a section On presheaf toposes with the essence of the definitions and statements from section 1.3 of Cisinki’s book.
I have been further expanding at Cisinski model structrure the section On presheaf toposes.
Effectively I am now translating the entire chapter 1.3 of Cisinki’s book and spelling out details that the book leaves out.
So far I have made it through all the preliminaries up to the main theorem stating the existence of the model structure.
Next I’ll try to translate / write out the full proof of that.
Thank you! I’m sure this will be a great thing to have.
Good to hear that you find this useful. Right now I need these notes as a script for a seminar talk where I will present the proof – or at least a good bit of it…
This morning, I have added a few more bits. The main new aspect for any potential reader is that I have added much more structure to the flow of the argument, see the new section outline at Cisinki model structure and the outline of the proof of the main theorem here. (Where “main theorem” still means “main theorem of section 1.3”, mind you.)
The main remaining gap as far as details for the proofs go is currently the last section. I’ll try to take care of that now.
Added to Cisinski model structure a handful of items on “localizers” on presheaf categories, here
added the remark that every Cisinski model structure is in particular combinatorial (and added an Examples-link the other way round).
