May I suggest you take a look at Section VII.2 of "Sheaves in Geometry and Logic", about tensoring functors (taking co-ends). An explicit description of how to compute such tensors is given. I suggest you work through yourself proving that the co-end I claim is in fact the same as Segal's construction, as doing this yourself will certainly make things much more clear for you than anything I can say. | |
