| Oct 10, 2013 at 16:14 | comment | added | Nicola | Did you try with "Bloch-Ogus" formalism/cohomology? \ell-adic and rigid cohomology are Bloch-Ogus (and mixed Weil too). Deligne-Beilinson cohomology is not mixed Weil, but its Bloch-Ogus. I remember that Beilinson uses the terminology "twisted Poincaré duality theory". | |
| Oct 10, 2013 at 15:56 | comment | added | ChrisLazda | No, their notion of a mixed Weil cohomology theory doesn't say anything about compact supports or Poincaré duality. It follows from their results that given a Weil cohomology theory, all the extra stuff pops out (by realising the motivic version), but it doesn't form part of their definition of a mixed Weil cohomology theory. | |
| Oct 10, 2013 at 15:43 | comment | added | David Loeffler | The abstract of the paper you link to refers to "mixed Weil cohomology theories" -- is their definition not what you want? | |
