Schwede's Du Bois and dense F-injective type conjecture

Let XX be a reduced scheme of finite type over an algebraically closed field of characteristic 00. A scheme is of dense FF-injective type if it has reductions to characteristic p>0p>0 that are FF-injective for a Zariski-dense set of primes. Schwede's conjecture. XX has Du Bois singularities if and only if XX is of dense FF-injective type. This conjecture proposes an equivalence between a characteristic-00 condition and the corresponding dense-characteristic-pp condition; the source records it as a conjecture, without resolving it.
