Abstract
Let F/K be a Galois extension of a number field of degree n, 𝒪
F
the ring of integers in F, and p a prime number which does not divide n. Let K
2 denote the Milnor K-functor. In this article, we shall study the structure of the odd part of the tame kernel K
2𝒪
F
of F by using the intermediate fields of F/K. In particular, for a multiquadratic field F, we shall get the p
i
-rank, (i > 0) of K
2𝒪
F
. Finally, we shall determine the structure of the odd parts of K
2𝒪
F
when where − 100 < d < 0, d
1 = 2,3,5,7.
