Vanilla 1.1.10 is a product of Lussumo. More Information: Documentation, Community Support.
When somebody asked me about the sSet enrichment of cosimplicial objects, I noticed that the nLab didn’t have the pointers. So I have now split off a stub cosimplicial object from simplicial object and added a bare minimum of pointers. No time for more at the moment.
There is no need to assume finite limits or colimits. I added an end formula for the hom-spaces: in effect, all we are doing is forming the totalisation of the cosimplicial simplicial set 𝒞(X•,Y•).
Thanks!
Actually, the question was about the simplicial tensoring.
Ah. Then you will need colimits in 𝒞.
I should have said it here as I did say it in the entry: what is called the “external simplicial structure” in Quillen 67, recalled for instance as Bousfield 03, section 2.10 involves the enrichment, the powering and the tensoring. That’s what I was pointing to. But I should have said so more clearly.
