| Jun 12, 2022 at 14:14 | comment | added | David White | To follow Simon's comment, in that 2016 preprint, Prasolov points out that there are substantial error's in the appendix B cited by David Corwin in 2013. Indeed, the author of that appendix published an erratum in 2015. | |
| May 11, 2016 at 11:21 | comment | added | Simon Henry | There is a new paper on the ArXiv that (claim to) answer the questions and a bit more (I haven't read it in detail yet and it is very recent, so maybe some care has to be taken...) : arxiv.org/abs/1605.01555 | |

| Feb 4, 2013 at 14:50 | comment | added | Leonid Positselski | I would be actually interested to see a reference discussing cosheafification of copresheaves of abelian groups or vector spaces in some detail. This being said, the OP's question as it is written at the moment is not very well-formed. What is a "pre-cosheaf in the category of vector spaces"? Pre-cosheaf of what, and over what? | |
| Feb 4, 2013 at 11:46 | comment | added | Dan Petersen | Is it clear that David's reference answers the question for cosheaves of vector spaces? The reference only deals with cosheaves of sets, and it's remarked there that the theories of cosheaves of sets and cosheaves of abelian groups are much more different than the theories of sheaves of sets vs. abelian sheaves. | |
