Prelog Chow groups of self-products of degenerations of cubic threefolds
Christian Böhning, Hans-Christian Graf von Bothmer, Michel van Garrel
It is unknown whether smooth cubic threefolds have an (integral Chow-theoretic) decomposition of the diagonal, or whether they are stably rational or not in general. As a first ste…

Prelog Chow rings and degenerations
Christian Böhning, Hans-Christian Graf von Bothmer, Michel van Garrel
For a simple normal crossing variety , we introduce the concepts of prelog Chow ring, saturated prelog Chow group, as well as their counterparts for numerical equivalence. Think…
