本文建立了一个从真实的闭域上适当的真正规簇的étale基本群重构真正规簇的étale基本群的几何子群的“群论”算法.
In the present paper, we establish a “group-theoretic” algorithm for reconstructing, from the étale fundamental group of a suitable proper normal variety over a real closed field, the geometric subgroup of the étale fundamental group of the proper normal variety.
