| Jun 29, 2013 at 21:18 | comment | added | Justin Smith | In Remark 3.5 of "Left-determined model categories and universal homotopy theories" (AMS Transactions vol 355) J. Rosicky and W. Tholen assert that $\eta_X$ is a trivial cofibration for all $X$. This is easily refuted (other statements in this paper have been shown to be false). | |
