Libro: Theory of economic changes: problems and decisions (978-5-396-00535-8) de Oleg S. Sukharev (URSS ) Comprar Libros de Economía .Economía .. Encuadernación: Rústica. The book develops the theory of institutional changes and presents a new direction of economic analysis: the institutional macroeconomics. The author develops the concept of economic dysfunction and applies it to the description of economic growth problems, offers a model of competition between agents within the "innovator-conservative" system, corrects the doctrine of "creative destruction", offers a model of institutional change based on the effect of the chessboard, with the resulting conclusions from the change in criteria for public well-being that are not fair in terms of institutional change. In addition, the monograph develops a system of axioms for the theory of economic systems efficiency, and proposes a system to assess the economic efficiency of system dysfunction, using the methods of the theory of reliability. The author analyzes the problems of the evolution of technical and financial systems and economies, showing a gap at the level of the fundamental principles of their joint development. 0 Introduction Chapter 1.

Libro: A new mathematical formalism: Skew-symmetric differential forms in mathematics, mathematical physics and field theory (978-5-396-00501-3) de PETROVA (URSS ) Comprar Libros de Ciencias Técnicas .Física .Mecánica Cuántica .. Encuadernación: Rústica. Skew-symmetric differential forms possess unique capabilities that manifest themselves in various branches of mathematics and mathematical physics. The invariant properties of closed exterior skew-symmetric differential forms lie at the basis of practically all invariant mathematical and physical formalisms. Closed exterior forms, whose properties correspond to conservation laws, explicitly or implicitly manifest themselves essentially in all formalisms of field theory. In the present work, firstly, the role of closed exterior skew-symmetric differential forms in mathematics, mathematical physics and field theory is illustrated, and, secondly, it is shown that there exist skew-symmetric differential forms that generate closed exterior differential forms. These skew-symmetric forms are derived from differential equations and possess evolutionary properties. The process of extracting closed exterior forms from evolutionary forms enables one to describe discrete transitions, quantum jumps, the generation of various structures, origination of such formations as waves, vortices and so on. In none of other mathematical formalisms such processes can be described since their description includes degenerate transformations and transitions from nonintegrable manifolds to integrable ones. The unique role played by skew-symmetric differential forms in mathematics and mathematical physics, firstly, is due to the fact that they are differentials and differential expressions, and, therefore, they are suitable for describing invariants and invariant structures. And, secondly, skew-symmetric forms have a structure that combines objects of different nature, namely, the algebraic nature of the form coefficients and the geometric nature of the base. The interaction between these objects enables to describe evolutionary processes, discrete transitions, the realization of conjugacy of operators or objects, the emergence of structures and observable formations, and so on. 0 Introduction Chapter 1.

Libro: Lectures in Geometry: Lie Groups and Lie Algebras (Semester V) (978-5-88417-024-7) de POSTNIKOV, M., Mikhail Mikhailovich Postnikov (Editorial URSS ) Comprar Libros de Ciencias Técnicas .. Encuadernación: cartoné The theory of Lie groups relies on Cartan's theorem on the equivalence of the category of simply connected Lie groups to that of Lie algebras. This book presents the proof of the Cartan theorem and the main results. The branches of the theory of Lie groups which rest on the Cartan theorem remain outside the limits of our exposition. The theory of Lie algebras has been developed to an extent necessary for the Cartan theorem to be proved. This book like the previous ones of this series* is a nearly faithful record of the Lectures delivered by the author at Moscow University to students (and postgraduates) of the Faculty of Mathematical Mechanics. However, while books I and II were based on Lectures of a compulsory course, this book is a record of an elective course, which makes it essentially different in a number of respects. 0 Preface. Lecture 1 Smooth and topological groups. Relaxing the conditions denning Lie groups. Examples of Lie groups. Cayley transformation. Further examples of Lie groups. Connected and arcwise connected spaces and groups. Reduction of any smooth groups to connected groups. Examples of connected Lie groups. Lecture 2 Left-invariant vector fields. Parallelizability of Lie groups. Integral curves of left-invariant vector fields and one-parameter subgroups. Lie functor. An example: a group of in-vertible elements of an associative algebra. Functions with values in an associative algebra. One-parameter subgroups of the group G (At). Lecture 3 Matrix Lie groups admitting the Cayley construction. A generalization of the Cayley construction. Groups possessing In-images. Lie algebras. Examples of Lie algebras. Lie algebras of vector fields. The Lie algebra of a Lie group. An example: the Lie algebra of a group of invertible elements of an associative algebra. Locally isomorphic Lie groups. Local Lie groups. Lie functor on the category of local Lie groups. Lecture 4 The exponent of a linear differential operator. A formula for the values of smooth functions in the normal neighbourhood of the identity of a Lie group.

Libro: Mechanics of elastic-plastic fracture: jundamentals of fracture mechanics (978-5-484-01022-6) de PARTON Z, V. (Editorial URSS ) Comprar Libros de Ciencias Técnicas .Física .Mecánica .. Encuadernación: rústica This book, comprising two volumes, presents current research and original investigations in the theory of large cracks capable of propagating and initiating partial or complete fracture in deformable solids. The book covers a wide variety of problems relating to the behavior of bodies with cracks, and ranges from crack extension criteria to the solution of complex problems of fracture mechanics. Also, the authors consider critical and subcritical states of equilibrium under single, multiple, thermal and dynamic loadings in elastic, viscoelastic, elastic-plastic and piezoelectrical bodies with cracks. Experimental methods for the determination of crack-resistance characteristics of materials are exposed. The first volume, which we present to the reader, is dedicated to the main criteria and methods of elastic and elastic-plastic fracture mechanics. Using real examples, the authors show the result of applying different fracture criteria for determining the critical and permissible length of a fracture under static or cyclic loadings. The second volume, published as a separate book, contains a systematic study of special problems of fracture mechanics. The book is intended for scientists and practicing engineers working in the field of fracture mechanics and also for post-graduates and senior students specializing in solid mechanics and strength of machine parts. Vladimir Zalmanovich Parton (1936-2001) Prof. V.Z.Parton was Head of Department of Higher Mathematics at the Institute of Chemical Engineering of Moscow. He was a well-known specialist in elasticity theory and fracture mechanics. He was a co-author of the books "Mathematical methods of the theory of elasticity" (1981), "Dynamics of brittle fracture" (1988), as well as the author of "Fracture Mechanics: from theory to practice" (1990; second edition, URSS, 2007). Evgenii Mikhailovich Morozov Prof. E M.Morozov works at the Department of Strength Physics of the Moscow Institute of Physics and Engineering. He is a recognized specialist in fracture mechanics and strength of solid bodies. Also, he was one of the pioneers of fracture mechanics in Russia. Prof. Morozov received the award of the Council of Ministers of the Soviet Union and the title of Honoured Worker of Science of the Russian Federation. E. M.
