Some remarks on pseudo-null submodules of tamely ramified Iwasawa modules
Some remarks on pseudo-null submodules of tamely ramified Iwasawa modules
We will give several observations about the structure of tamely ramified Iwasawa modules for a ℤ p -extension (or a multiple ℤ p -extension) of an algebraic number field. In the present paper, we consider the question whether a given tamely ramified Iwasawa module has a non-trivial finite (or pseudo-null) …
