摘要

我们证明了具有正特征的光滑del Pezzo品种是拟F$ F$分裂的。为此，我们引入了弱拟F$ F$分裂，并证明了光滑del Pezzo品种的一般阶梯是正规的。

Weak quasi- F $F$ -splitting and del Pezzo varieties

We show that smooth del Pezzo varieties in positive characteristic are quasi- $F$ -split. To this end, we introduce weak quasi- $F$ -splitting and we prove that general ladders of smooth del Pezzo varieties are normal.
