This         exposition is aimed at readers\nwith some background in either of these two  fields. Emphasis\nis given to the notion of a normal basis, which allows     one\nto view in a well-known conjecture in number theory\n(Leopoldt's     conjecture) from a new angle. Methods to\nconstruct certain extensions quite explicitly are also\ndescribed at length.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783540563501\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783540563501","offer_id":39436737380445,"sku":"9783540563501","price":26.7,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/a5cdebfb-6ef8-433f-80ef-35b857b3e18b.jpg?v=1772258655","url":"https:\/\/shop.autorenwelt.de\/products\/cyclic-galois-extensions-of-commutative-rings-von-cornelius-greither","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
