non-Archimedean geometry中的奇异半正度量

Singular semipositive metrics in non-Archimedean geometry

S. Boucksom, C. Favre, M. Jonsson

摘要:

设X是剩余特征为零的完备离散赋值域K上的光滑射影Berkovich空间,赋以充足的线丛L.我们引入了L上(可能是奇异的)半正(或多重次调和)度量的一般概念,并证明了在复情形下类似于下面两个基本结果:半正度量集是紧模常数,每个半正度量是光滑半正度量的递减极限.特别地,对于连续度量,我们的定义与S. W.张某证明使用乘子理想和建设合适的模型X的赋值环的K,使用环形技术。

英文摘要:

Let X be a smooth projective Berkovich space over a complete discrete valuation field K of residue characteristic zero, endowed with an ample line bundle L. We introduce a general notion of (possibly singular) semipositive (or plurisubharmonic) metrics on L, and prove the analogue of the following two basic results in the complex case: the set of semipositive metrics is compact modulo constants, and each semipositive metric is a decreasing limit of smooth semipositive ones. In particular, for continuous metrics our definition agrees with the one by S.-W. Zhang. The proofs use multiplier ideals and the construction of suitable models of X over the valuation ring of K, using toroidal techniques.
