A mathematical introduction to the theory and applications of logic and set theory with an emphasis on writing proofs Highlighting the applications and notations of basic mathematical concepts within the framework of logic and set theory, A First Course in Mathematical Logic and Set Theory introduces how logic is used to prepare and structure proofs and solve more complex problems. The book begins with propositional logic, including two-column proofs and truth table applications, followed by first-order logic, which provides the structure for writing mathematical proofs. Set theory is then introduced and serves as the basis for defining relations, functions, numbers, mathematical induction, ordinals, and cardinals. The book concludes with a primer on basic model theory with applications to abstract algebra. A First Course in Mathematical Logic and Set Theory also includes: Section exercises designed to show the interactions between topics and reinforce the presented ideas and concepts Numerous examples that illustrate theorems and employ basic concepts such as Euclid’s lemma, the Fibonacci sequence, and unique factorization Coverage of important theorems including the well-ordering theorem, completeness theorem, compactness theorem, as well as the theorems of Lowenheim–Skolem, Burali-Forti, Hartogs, Cantor–Schroder–Bernstein, and Konig An excellent textbook for students studying the foundations of mathematics and mathematical proofs, A First Course in Mathematical Logic and Set Theory is also appropriate for readers preparing for careers in mathematics education or computer science. In addition, the book is ideal for introductory courses on mathematical logic and/or set theory and appropriate for upper-undergraduate transition courses with rigorous mathematical reasoning involving algebra, number theory, or analysis.


Brazilian Jiu-Jitsu: Theory and Technique Brazilian Jiu-Jitsu: Theory and Technique

Автор: Gracie Renzo, Gracie Royler, Danaher John

Год издания: 

During the last decade, the martial arts world has looked to innovative mixed martial arts competitions such as the Ultimate Fighting Championship to determine which fighting style is the best. These contests have repeatedly shown the grappling style of martial arts, headed by Brazilian jiu-jitsu, to dominate. The Brazilian jiu-jitsu style stems from the premise, garnered from analysis of actual street fights, that the outcome of any fight is decided on the ground. While most martial arts deal only with the initial punching and kicking stages of combat, Brazilian jiu-jitsu concentrates on ground combat. This guide shows how to use Brazilian jiu-jitsu to increase combat effectiveness. Photographs and step-by-step instructions show how to master the techniques used in this exciting new form of combat. Renzo Gracie, a two-time world Abu Dhabi submission jiu-jitsu champion, two-time Brazilian national champion, World Combat champion, and Martial Arts Reality Superfight champion, teaches Brazilian jiu-jitsu at an elite martial arts academy. Royler Gracie has competed in the Black Belt ranks for 20 years, winning the world title four times and the Abu Dhabi world submission championship for two consecutive years. They live in New York City.

Theory and practical aspects of Internationa settlements. Economic cooperation Theory and practical aspects of Internationa settlements. Economic cooperation

Автор: Николай Камзин

Год издания: 

As part of the dynamics of international economic cooperation by the need for mutual settlement operations, so the problem of organization of settlements is an important place for the economically active subjects, especially in a globalized economic space in the functioning of transnational structures and scale of the export, import and international financial transactions. In agreeing on the order of calculations, the participants determined the form of payment in order to fulfill the financial obligations of the agreement – regulated by means of voluntary compliance through a credit institution liabilities, characterized by specific features on the order of transfer of funds to the account, a certain kind of settlement document, as well as office procedures. The source of payment relations is the need to have one contractor expressed in the appropriate disposition, the other in shortage. This relationship gives rise as a consequence of the relationship with the lending institution. Need to accession will intensify in the subjects of international payment relationship.


Об адекватности систем имитационного моделирования GPSS World и AnyLogic (продолжение) Об адекватности систем имитационного моделирования GPSS World и AnyLogic (продолжение)

Автор: В. Д. Боев

Год издания: 

Автор демонстрирует адекватность GPSS World и AnyLogic относительно результатов моделирования. Поскольку система AnyLogic, в отличие от системы GPSS и, в частности, версии GPSS World, пока не имеет длительной истории применения, более детально демонстрируются методика и приемы моделирования в системе AnyLogic.


Об адекватности систем имитационного моделирования GPSS World и AnyLogic (начало) Об адекватности систем имитационного моделирования GPSS World и AnyLogic (начало)

Автор: В. Д. Боев

Год издания: 

При изучении в рамках различных дисциплин имитационного моделирования, а также в практике создания моделей возникает вопрос о выборе среды разработки, адекватности систем моделирования. В статье на реализованных средствами GPSS World и AnyLogic моделях объектов с разнородными протекающими в них процессами демонстрируется адекватность GPSS World и AnyLogic относительно результатов моделирования. Поскольку применение GPSS World имеет давнее и большее распространение, автором на примерах подробно изложены методики моделирования в AnyLogic.
