Lecture notes in physics 211

"Resonances - Models and Phenomena" originated during the Research Year "Project No. 2 - Mathematics + Physics" at the Centre for Interdisciplinary Research (ZiF) of Bielefeld University. Project No. 2 has brought more than a hundred mathematicians and physicists from 25 nations to Bielefeld for extended periods of residence with the purpose of studying problems, concepts and methods in an interdisciplinary setting.

Ҳақиқат ва адолат қуёши

Ушбу китобга муаллифнинг тўртта катта ҳажмли мақоласи киритилган бўлиб, уларнинг дастлабкисида янги ўзбек адабиётининг асосий хусусиятлари тўғрисида мулоҳаза юритилади. Мазкур хусусиятларни очишда муаллиф янги ўзбек адабиёти тарихининг кўплаб асосий муаммоларини ҳозирги давр нуқтаи назаридан янгича талқин қилишга интилган. Китобдаги кейинги мақолалар яқин ўтмиш ва ҳозирги адабиётимизнинг ҳамда танқидчилигимизнинг баъзи намуналарини муфассал таҳлил қилишга бағишланган.

One of the main results in the theory of optimal control processes is the Pontryagin Maximum Principle which states a necessary condition for a control to be optimal. The aim of these notes is to prove that the Pontryagin condition holds for a larger class of controls, characterized by a geometric rather than variational property. More precisely, it will be shown that for a given control vector field on a finite-dimensional manifold of class , p $ 3 , any control steering a point of the manifold to the boundary of its set of attainability satisfies the condition mentioned above.

Конспект лекций «Методология научного творчества».

Конспект лекций является основным руководящим документом для магистрантов вступающих к творческой научной деятельности. Он охватывает начальные понятия творческой деятельности, методы экспериментальных исследований, их достоинства и недостатки, аналитические методы и эталоны теоретических подходов. Кроме того, дает представления о критериях научности в решении задач различных сфер научной деятельности. Наряду с этим в конспекте даются линии с потерями и без потерь. В исследованиях жидких материалов освещены вопросы гетерогенных и гомогенных сред. Все эти вопросы связаны с устойчивостью и корректностью поставленных задач, которые расширяет круг лиц обучающихся в бакалавриатуре, магистратуре и особенно в аспирантуре.

Algorithm 748. Enclosing Zeros of Continuous Functions

Two efficient algorithms for enclosing a zero of a continuous function are presented. They are similar to the recent methods, but together with quadratic interpolation they make essential use of inverse cubic interpolation as well. Since asymptotically the inverse cubic interpolation is always chosen by the algorithms, they achieve higher-efficiency indices: 1.6529... for the first algorithm, and 1.6686... for the second one. It is proved that the second algorithm is optimal in a certain family. Numerical experiments show that the two new methods compare well with recent methods, as well as with the efficient solvers of Dekker, Brent, Bus and Dekker, and Le. The second method from the present article has the best behavior of all 12 methods especially when the termination tolerance is small.

Elementary concepts of topology

I have made no attempt to revise it, but have merely tried to preserve it in its proper historical perspective, and have made only a few minor modifications and corrections in the process. I have inserted a footnote and several parenthetical notes in an effort to clarify the material or to indicate the current terminology, and have actually changed the notation in several places (notably that for the homology groups) to avoid confusion and to bring it into consonance with modern usage.

Бизнес по-еврейски : 67 золотых правил

В этой небольшой книге приводятся уникальные правила ведения бизнеса, созданные древними мудрецами много лет назад, которые удивительно современны и как никогда актуальны для бизнеса XXI века. Так может быть, именно эти правила, передающиеся на генном уровне от одного поколения евреев к другому, позволяют создавать огромные финансовые состояния? Об этом не пишут в учебниках по маркетингу, но подавляющее большинство мировой бизнес-элиты соблюдает те золотые правила, которые изложены в этой книге.

Geometry of Spaces of Constant Curvature

Spaces of constant curvature, i.e. Euclidean space, the sphere, and Loba- chevskij space, occupy a special place in geometry. They are most accessible to our geometric intuition, making it possible to develop elementary geometry in a way very similar to that used to create the geometry we learned at school. However, since its basic notions can be interpreted in different ways, this geometry can be applied to objects other than the conventional physical space, the original source of our geometric intuition.
