The basic question, still open as of, is whether there is a cycle map:
If X is smooth, such a map exists since is the usual Chow ring of X. (Totaro 2014) harv error: no target: CITEREFTotaro2014 (help) has shown that there might not be such a map even if X is a linear variety, roughly a variety admitting a cell decomposition.
is the usual References
