I wish we had one straight convention which everyone followed throughout, or at least a small number thereof. It would be great to have an automated "convention translator" for these signs and so on, otherwise it's hell trying to cite results out of various papers and make sure their sign conventions agree with yours (and often they do not). | |
| Aug 26, 2010 at 1:59 | comment | added | Tyler Lawson | The reason for the convention is that, using the Alexander-Whitney convention, you get a left module structure if you apply to the righthand factor and you get a right module structure if you apply to the lefthand factor. Fun related topics include trying to get the signs correct on the dual of a differential graded coalgebra. | |
