Jun 30, 2010 at 2:56 | comment | added | Victor Protsak | Concerning your motivation (3), the non-canonical aspect can be turned into an advantage: it's a manifestation of non-trivial structures on various "categorifications" (cf Bernstein, Frenkel, Khovanov in the Schur-dual situation of $\mathfrak{gl}_n$-modules). | |

Jun 29, 2010 at 21:45 | comment | added | darij grinberg | I am going to replace it by "ugly" anyway because the actual meaning of evil ( ncatlab.org/nlab/show/evil ) seems to have nothing to do with the one I want (uncanonical, unconstructive, uses restrictive assumption, requires non-elegant proofs). | |
Jun 29, 2010 at 21:16 | comment | added | Victor Protsak | I don't think "how evil" is an appropriate expression to use in a title of a mathematical question. | |
