题目：Some related problems about Frobenius splitting varieties.

报告人: 刘丛军 中国科学院数学与系统科学研究院(博士)

摘要：A variety X in characteristic p is called Frobenius split if there is a "p-th root" map σ: X→X, that is, an additive map satisfying σ(f^pg)=fσ(g) and σ(1)=1 (in particular, σ(f^p)=f, so that σ is an O_X-linear splitting of the Frobenius map F: O_X→F_*(O_X). Such varieties enjoy very nice properties. In this talk, We will give some example of Frobenius splitting variety. In addition, I continue to introduce some questions about Frobenius splitting variety.
