At homotopy coend I have added a pointer to the section at Quillen bifunctor on Quillen bifunctor properties of coends over tensors here.

Created coend in a derivator,

Interesting. I keep saying to Moritz (who is here) that we should go through lists of applications of derivators such as this, in order to fill the theory with life. But for the time being we seem to be both too busy and travelling too much to get around to it.

I added to coend in a derivator a fourth construction using the twisted arrow category, which I learned from Moritz.
