正特征测井曲面的极小模型与丰度

Minimal models and abundance for positive characteristic log surfaces

Hiromu Tanaka

摘要:

讨论了正特征奇异曲面的双有理几何。更确切地说,我们建立了Q-阶乘曲面和对数正则曲面的极小模型程序和丰度定理。此外,在基域是有限域的代数闭包的情况下,我们在更弱的假设下得到了同样的结果。

英文摘要:

We discuss the birational geometry of singular surfaces in positive characteristic. More precisely, we establish the minimal model program and the abundance theorem for Q-factorial surfaces and for log canonical surfaces. Moreover, in the case where the base field is the algebraic closure of a finite field, we obtain the same results under much weaker assumptions.
