Title: ON THE COHOMOLOGICAL CHARACTERIZATION OF REAL FREE PRO-2-GROUPS
Author: ENGLER, AJ
Abstract: The aim of this note is to give a cohomological characterization of the real free pro-2-groups. The real free pro-2-groups are the free pro-2-product of copies of Z/2Z with a free pro-2-group. They are characterized as the pro-2-groups G for which there exists a character chi(0), whose kernel is a free pro-2-g roup, such that chi(0) boolean OR chi = chi boolean OR chi, for every chi is an element of H-1(G). We discuss the naturalness of these conditions and we state some relations between them and field arithmetic properties.
