| Oct 18, 2011 at 19:19 | comment | added | Martin Brandenburg | Funny, the same questions came to me a couple of hours ago. I think the equation $A \otimes_R B = \int^{R} A \otimes B$ is quite illuminating. Also in general, the intuition is perhaps that we gather all $F(c,c)$ together and identify the right $C$-action with the left $C$-action. I doubt that (co)ends have a precise relationship with integrals in measure theory, but there are some formal similarities, such as the representation as weighted sums and Fubini's Theorem. | |
