Correction of two typos, pointer to Tim Porter's comment and addition of a small mathematical point

| Apr 16, 2011 at 1:08 | comment | added | Akhil Mathew | Dear Jonathan: thanks! I hadn't heard of Thomason's model structure, and was only really aware of the concrete example of simplicial sets as being a good model for classical homotopy theory. (I'll have to look up Quillen's Theorem A and B, as well.) | |

| Apr 15, 2011 at 9:14 | comment | added | Tim Porter | Jonathan: you say: 'As regards Grothendieck's opinion of Thomason's model structure, I do not know.' The point was made in a letter to me in the middle of the time when he was writing PS. (The letter was to have been included in Maltsinitios' retyping of the PS correspondence but that was stopped by Grothendieck. He does mention Thomason's work (in fact, he learnt of that at least partially from me and was surprised by the result.) I think he makes some comments about the cofibrations not being that intuitive or geometric. | |
