THE SECOND p-CLASS GROUP OF A NUMBER FIELD
THE SECOND p-CLASS GROUP OF A NUMBER FIELD
For a prime p ≥ 2 and a number field K with p-class group of type (p, p) it is shown that the class, coclass, and further invariants of the metabelian Galois group [Formula: see text] of the second Hilbert p-class field [Formula: see text] of K are determined by …
