Investments in Telecoms and Growth in Productivity
ISBN: 9783659283796 / Angielski / Miękka / 2013 / 424 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The goal of this study is to investigate a link between investments in telecoms, a common subset of investments in information and communication technology and economic growth in the context of countries that are classified by the international community as transition economies. More specifically, in this study we focus on the relationship between telecoms and one of the determinants of economic growth, total factor productivity. Neoclassical growth accounting and the theory of complementarity provide the theoretical framework on which we build this research. By combining the data obtained...

Elements of the Mathematical Theory of Multi-Frequency Oscillations
ISBN: 9780792314387 / Angielski / Twarda / 1991 / 313 str. Termin realizacji zamówienia: ok. 20 dni roboczych. Translated from the original Russian edition of 1987 (Nauka, Moscow), this volume deals with the theory of multi-frequency oscillations as a motion of a dynamical system which describes a recurrent trajectory on an invariant toroidal manifold of the system. In this way, the invariant toroidal manifo

Elements of Mathematical Theory of Evolutionary Equations in Banach Spaces
ISBN: 9789814434829 / Angielski / Twarda / 2013 / 408 str. Termin realizacji zamówienia: ok. 22 dni roboczych. Evolutionary equations are studied in abstract Banach spaces and in spaces of bounded number sequences. For linear and nonlinear difference equations, which are defined on finite-dimensional and infinite-dimensional tori, the problem of reducibility is solved, in particular, in neighborhoods of their invariant sets, and the basics for a theory of invariant tori and bounded semi-invariant manifolds are established. Also considered are the questions on existence and approximate construction of periodic solutions for difference equations in infinite-dimensional spaces and the problem of...

Qualitative and Asymptotic Analysis of Differential Equations with Random Perturbations
ISBN: 9789814329064 / Angielski / Twarda / 2011 / 324 str. Termin realizacji zamówienia: ok. 22 dni roboczych. Differential equations with random perturbations are the mathematical models of real-world processes that cannot be described via deterministic laws, and their evolution depends on random factors. The modern theory of differential equations with random perturbations is on the edge of two mathematical disciplines: random processes and ordinary differential equations. Consequently, the sources of these methods come both from the theory of random processes and from the classic theory of differential equations. This work focuses on the approach to stochastic equations from the perspective of...

'Et moi, ..., si j'avait su comment en revenir, One service mathematics has rendered the human race. It has put common sense back je n'y serais point aile.' where it belongs, on the topmost shelf next Jules Verne to the dusty canister labelled 'discarded n- sense'. The series is divergent; therefore we may be Eric T. Bell able to do something with it. O. Hcaviside Mathematics is a tool for thought. A highly necessary tool in a world where both feedback and non- linearities abound. Similarly, all kinds of parts of mathematics seNe as tools for other parts and for other sciences. Applying a...

Creating Theoretical Research Frameworks using Multiple Methods: Insight from ICT4D Investigations
ISBN: 9781032476544 / Angielski / Miękka / 2023 / 420 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. By now, it is commonly accepted that investments in information and communication technologies (ICTs) can facilitate macroeconomic growth in developed countries. Research standards in ICT for development (ICT4D) are high, and it is a basic expectation that a theoretically sound conceptual investigation should yield actionable results. An additional expectation is that an on-the-ground study conducted in each setting should add to the common body of knowledge based on theory. In other words, one is expected to make a connection between the world of concepts and the world of reality....

Dichotomies and Stability in Nonautonomous Linear Systems
ISBN: 9780415272216 / Angielski / Twarda / 2002 / 400 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. Linear nonautonomous equations arise as mathematical models in mechanics, chemistry, and biology. The investigation of bounded solutions to systems of differential equations involves some important and challenging problems of perturbation theory for invariant toroidal manifolds. This monograph is a detailed study of the application of Lyapunov functions with variable sign, expressed in quadratic forms, to the solution of this problem. The authors explore the preservation of invariant tori of dynamic systems under perturbation. This volume is a classic contribution to the literature on...

Numerical-Analytic Methods in Theory of Boundary- Value Problems
ISBN: 9789810236762 / Angielski / Twarda / 2000 / 468 str. Termin realizacji zamówienia: ok. 22 dni roboczych. This book contains the main results of the authors' investigations on the development and application of numerical-analytic methods for ordinary nonlinear boundary value problems (BVPs). The methods under consideration provide an opportunity to solve the two important problems of the BVP theory — namely, to establish existence theorems and to build approximation solutions. They can be used to investigate a wide variety of BVPs.The Appendix, written in collaboration with S I Trofimchuk, discusses the connection of the new method with the classical Cesari, Cesari-Hale and...

Multifrequency Oscillations of Nonlinear Systems
ISBN: 9781402020308 / Angielski / Twarda / 2004 / 317 str. Termin realizacji zamówienia: ok. 20 dni roboczych. In contrast to other books devoted to the averaging method and the method of integral manifolds, in the present book we study oscillation systems with many varying frequencies. In the process of evolution, systems of this type can pass from one resonance state into another. This fact considerably complicates the investigation of nonlinear oscillations. In the present monograph, a new approach based on exact uniform estimates of oscillation integrals is proposed. On the basis of this approach, numerous completely new results on the justification of the averaging method and its...

Methods of Accelerated Convergence in Nonlinear Mechanics
ISBN: 9783642619021 / Angielski / Miękka / 2011 / 291 str. Termin realizacji zamówienia: ok. 20 dni roboczych. This monograph deals with some of the latest results in nonlinear mechanics, obtained recently by the use of a modernized version of Bogoljubov's method of successive changes of variables which ensures rapid convergence. This method visualised as early as 1934 by Krylov and Bogoljubov provides an effective tool for solving many interesting problems of nonlinear mechanics. It led, in particular, to the solution of the problem of the existence of a quasi periodic regime, with the restriction that approximate solutions obtained in the general case involved divergent series. Recently, making use...
