Feb 7, 2012 at 23:14 | comment | added | Moosbrugger | If f^* has a left adjoint, then f^* is left exact. I.e., f is flat. | |
Feb 7, 2012 at 16:31 | comment | added | Donu Arapura | I have to teach in a few minutes, so I might be overlooking something, but $f_!$ should coincide with $f_*$ when $f$ is proper. So this case should be OK. | |
