Arakelov几何新探

New Approach to Arakelov Geometry

Nikolai Durov

摘要:

这项工作是致力于一个新的完全代数的方法来阿拉克洛夫几何,这并不要求正在考虑的品种是一般光滑或投影。为了构造这样一种方法,我们发展了一种广义环和概型理论,它包括经典环和概型以及“奇异”对象,如F_1(“一元域”),Z_ \infty(“实整数”),T(热带数)等,从而提供了一种研究这些物体的系统方法。这种广义环和概型理论发展到代数K理论、相交理论和Chern类的构造。然后证明了Q上代数簇的Arakelov模型的存在性,并将我们的一般结果应用于这类模型。

英文摘要:

This work is dedicated to a new completely algebraic approach to Arakelov geometry, which doesn't require the variety under consideration to be generically smooth or projective. In order to construct such an approach we develop a theory of generalized rings and schemes, which include classical rings and schemes together with "exotic" objects such as F_1 ("field with one element"), Z_\infty ("real integers"), T (tropical numbers) etc., thus providing a systematic way of studying such objects. This theory of generalized rings and schemes is developed up to construction of algebraic K-theory, intersection theory and Chern classes. Then existence of Arakelov models of algebraic varieties over Q is shown, and our general results are applied to such models.
