| Jan 10, 2014 at 4:13 | comment | added | Mariano Suárez-Álvarez | I described the d_2 in the change-of-rings spectral sequence in arXiv:0707.3210 as a Yoneda product. I am pretty sure the LHS s.s. is the same as the appropriate change-of-rings s.s. For example, in Hochschild cohomology (which is the situation I was interested in) the differentials are cup products with the a sequence of characteristic classes of the algebra extension, generalizing the class in $H^2$ described originally by Hochschild. | |
