When it appeared in 1949 it was a pioneer. Now there are plenty of competing accounts. But Hasse has something extra to offer. This is not surprising, for it was he who inaugurated the local-global principle (universally called the Hasse principle). This doctrine asserts that one should first study a problem in algebraic number theory locally, that is, at the completion of a vaulation. Then ask for a miracle: that global validity is equivalent to local validity. Hasse proved that miracles do happen in his five beautiful papers on quadratic forms of 1923-1924. ... The exposition is discursive. ... It is trite but true: Every number-theorist should have this book on his or her shelf.\" \n                \n                \u003cbr\u003e\n                                (Irving Kaplansky in Bulletin of the American Mathematical Society, 1981)\n            \n            \u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783540427490\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783540427490","offer_id":39424796098653,"sku":"9783540427490","price":58.84,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/ce646cd7-6ae6-4ac0-beb5-926e14d3bdd6.jpg?v=1772171822","url":"https:\/\/shop.autorenwelt.de\/en\/products\/number-theory-von-helmut-hasse","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
