In mathematics , specifically commutative algebra , Hilbert's basis theorem says that a polynomial ring over a Noetherian ring is Noetherian. Hilbert's Basis Theorem. This can be translated into algebraic geometry as follows: every algebraic set over a field can be described as the set of common roots of finitely many polynomial equations.

In mathematics , more specifically in the area of abstract algebra known as ring theory , a Noetherian ring is a ring that satisfies the ascending chain condition on left and right ideals ; that is, given any increasing sequence of left or right ideals:. Noetherian rings are named after Emmy Noether. The notion of a Noetherian ring is of fundamental importance in both commutative and noncommutative ring theory, due to the role it plays in simplifying the ideal structure of a ring. For instance, the ring of integers and the polynomial ring over a field are both Noetherian rings, and consequently, such theorems as the Lasker—Noether theorem , the Krull intersection theorem , and Hilbert's basis theorem hold for them. Furthermore, if a ring is Noetherian, then it satisfies the descending chain condition on prime ideals. This property suggests a deep theory of dimension for Noetherian rings beginning with the notion of the Krull dimension. For noncommutative rings , it is necessary to distinguish between three very similar concepts:.

Throughout this paper, a monoid means a commutative semigroup with identity element. The operation is written additively and the identity element is denoted by 0, unless otherwise stated. The set supp f is called the support of f. For more details on the ring of generalized power series, the readers can refer to [ 1 , 2 , 3 ]. In [ 5 , Proposition 2. Thus, we recover [ 5 , Proposition 2. For the most part of the proof, we follow the proof of [ 2 , 5.

Researchers in ring theory or allied topics, such as the representation theory of finite dimensional Lie algebras, will appreciate this collection of expository lectures on advances in ring theory and their applications to other areas. Five of the lectures were delivered at a conference on Noetherian rings at the Mathematisches Forschungsinstitut, Oberwolfach, in January , and the sixth was delivered at a London Mathematical Society Durham conference in July The study of the prime and primitive ideal spectra of various classes of rings forms a common theme in the lectures, and they touch on such topics as the structure of group rings of polycyclic-by-finite groups, localization in noncommutative rings, and rings of differential operators. The lectures require the background of an advanced graduate student in ring theory and may be used in seminars in ring theory at this level. AMS Homepage. Join our email list. Sign up.

This article consists of a collection of problems in Commutative Ring Theory sent to us, in response to our request, by the authors of articles in this volume. It also includes our contribution of a fair number of unsolved problems. Some of these one hundred problems already appear in other articles of this volume; some are related to the topics but do not appear in another article; yet others are problems unrelated to any of the articles, but that the authors consider of importance. For all problems, we gave a few useful references, which will lead readers to other relevant references. There is no attempt to be encyclopedic. We added definitions and clarifying comments to make the problems more self contained, but, as a rule, if undefined notions are used the reader can find the relevant definitions in the cited references.

 Это очень большие деньги. - Конечно. Договорились. Девушка покачала головой. - Как бы я хотела сказать .

Он же вас ненавидит. - Он позвонил и предупредил, что заканчивает работу над алгоритмом, создающим абсолютно стойкие шифры. Я ему не поверил. - Но зачем он вам об этом сообщил? - спросила Сьюзан.  - Хотел предложить вам купить этот алгоритм.

Собор был уже совсем рядом, он это чувствовал. Толпа стала еще плотнее, а улица шире. Они двигались уже не по узкому боковому притоку, а по главному руслу. Когда улица сделала поворот, Беккер вдруг увидел прямо перед собой собор и вздымающуюся ввысь Гиральду. Звон колоколов оглушал, эхо многократно отражалось от высоких стен, окружающих площадь. Людские потоки из разных улиц сливались в одну черную реку, устремленную к распахнутым дверям Севильского собора. Беккер попробовал выбраться и свернуть на улицу Матеуса-Гаго, но понял, что находится в плену людского потока.

Мысли ее смешались. Хоть бы замолчала эта омерзительная сирена. Почему Стратмор отмел такую возможность. Хейл извивался на полу, стараясь увидеть, чем занята Сьюзан. - Что .

 Вы меня слышите? - вмешался Беккер, чувствуя себя неловко.  - Вы все время говорите о произвольном наборе букв. Мне кажется, я должен вам сказать… что это не случайный набор букв. Все на подиуме воскликнули: - Что. В голосе Беккера слышались извиняющиеся нотки: - Простите, но это определенно осмысленные слова.

 Mala suerte, - вздохнул лейтенант.  - Не судьба. Собор закрыт до утренней мессы. - Тогда в другой.  - Беккер улыбнулся и поднял коробку.
