There's something I want to do with Haskell, and after tinkering for a while I think it's not possible. Before giving up entirely, I thought I'd try this mailing list. I'm working on an abstract algebra library, using the "types are sets" strategy. For the algebraists out there, I'm trying to implement as much as I can of "Abstract Algebra" by Dummit & Foote in Haskell. I've got a Ring class definition that looks approximately like
It follows my usual pointer to NumericPrelude where some algebraic structures are implemented including residue classes. However a quotient by a general ideal is missing. http://darcs.haskell.org/numericprelude/src/Number/ResidueClass/Func.hs http://hackage.haskell.org/cgi-bin/hackage-scripts/package/numeric-prelude _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
