Equality, similarity, order: popular introduction to the theory of binary relations. 2nd edition

In the book proposed by the readers written by a famous mathematician, cybernetic and philosopher Yu. A. Schreider, it is told about how to formally describe the properties of the relations that are familiar to all indicated in the title. This example turns out how the transition from the usual, but inaccurate concepts to strict mathematical definitions occurs. The need for a strict description of the simplest relations arises in mathematical logic, cybernetics, mathematical linguistics, etc. The last chapter of the book is devoted to the simplest examples from mathematical linguistics. The algebra of the relationship described in the book is told quite publicly, and the book can be recommended to high school students engaged in mathematical circles; linguists developing mathematical models of the language; students of humanitarian specialties in need of a certain mathematical education; scientists engaged in any aspects of cybernetics; as well as a wide range of readers, including not mathematicians by profession.
