| 释义 |
In number theory, a Parshin chain is a higher-dimensional analogue of a place of an algebraic number field. They were introduced by {{harvtxt|Parshin|1978}} in order to define an analogue of the idele class group for 2-dimensional schemes. A Parshin chain of dimension s on a scheme is a finite sequence of points p0, p1, ..., ps such that pi has dimension i and each point is contained in the closure of the next one. References
