Etale wild kernels of exceptional number fields, by Kevin Hutchinson

We clarify the relationship between higher etale wild kernels of a number field at the prime 2 and the Galois-coinvariants of Tate-twisted class groups in the 2-cyclotomic tower of the field. We also determine the relationship between the etale wild kernel and the group of infinitely divisible elements of second cohomology group of the field with values in Tate-twisted 2-adic integers.
