Kollár–Takagi–Tanaka–Witaszek–Yasuda–Yoshikawa log-resolution lifting conjecture for log del Pezzo pairs
Kollár–Takagi–Tanaka–Witaszek–Yasuda–Yoshikawa log-resolution lifting conjecture for log del Pezzo pairs
Let be a log del Pezzo pair over a perfect field of characteristic , with standard coefficients. A log resolution is a resolution such that the relevant boundary and exceptional divisors have simple normal crossings. Then there exists a log resolution of such that the pair
lifts to , the ring of Witt vectors of the field . Kollár–Takagi–Tanaka–Witaszek–Yasuda–Yoshikawa's conjecture. Every such pair admits a log resolution whose resolved pair lifts to the Witt vectors. This conjecture is recalled from the cited source; the supplied text gives no resolution status.
