Hi all! Thank you very much for all your comments and your help to improve my general knowledge! I guess these are things that one would learn at school, but I never learned English in a formal setting over a period of more than 4 weeks. At school I just had German, Latin, French and Ancient Greek, and at university I had one semester of Akkadian...
Back to "a" vs "an": If it depends on pronunciation then I doubt that there is an easy algorithm. So, I have to look for a way around. I can not say "the", because my problem comes from the __repr__ method of cochains (or actually cocycles, but I thought that cocycles are cochains, after all). It would, for example return c_2_2*b_1_0^6+c_2_2^3*b_1_0^2, a 8-Cochain in H^*(D8; GF(2)) In general, it starts with either a custom name or a construction description. The construction description may be "0", therefore I add information on the degree and the cohomology ring it belongs to. And since the cohomology ring contains more than one cochain class, I can't say "the cochain". Perhaps this is a way out: c_2_2*b_1_0^6+c_2_2^3*b_1_0^2: 8-Cochain in H^*(D8; GF(2)) Cheers, Simon --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
