| May 7, 2010 at 1:41 | comment | added | Mike Shulman | The notation is also otherwise pretty nonstandard; I've never seen $f_\wedge$ and $f^\wedge$ and $f_+$ used in this way. Much more common is $f_! \dashv f^* \dashv f_*$. | |

| May 6, 2010 at 22:49 | comment | added | André Henriques | It seems that $C^\wedge$ denotes the category of presheaves of sets on $C$ (i.e. functors from $C^{\mathit{op}}$ to $\mathit{Set}$). This is not made explicit in the question, I just add this remark for clarity. | |
