  • Mathematics is the science study of the number, structure, and spatial transformations. In other words, it is assumed that subjects' shape and number. "According to the official view, it is the study of the abstract structure defined from the axioms, using Logic (logic) and mathematical symbols. The other point of it is described in mathematical philosophy. Due to their wide applications in many science, mathematics is known as the "universal language". Experts in the field of mathematics known as mathematicians....

  • This book focuses on the Fourier transform applications in the analysis of some types of materials. The field of Fourier transform has seen explosive growth during the past decades, as phenomenal advances both in research and application have been made. During the preparation of this book, we found that almost all the textbooks on materials analysis have a section devoted to the Fourier transform theory. Most of those describe some formulas and algorithms, but one can easily be lost in seemingly incomprehensible mathematics....

  • The long-awaited sequel to the "Concepts and Practice of Mathematical Finance" has now arrived. Taking up where the first volume left off, a range of topics is covered in depth. Extensive sections include portfolio credit derivatives, quasi-Monte Carlo, the calibration and implementation of the LIBOR market model, the acceleration of binomial trees, the Fourier transform in option pricing and much more. Throughout Mark Joshi brings his unique blend of theory, lucidity, practicality and experience to bear on issues relevant to the working quantitative analyst....

  • Russian mathematics (later Soviet mathematics, and Russian mathematics once again) occupies a special place in twentieth-century mathematics. In addition to its well-known achievements, Russian mathematics established a unique style of research based on the existence of prominent mathematical schools. These schools were headed by recognized leaders, who became famous due to their talents and outstanding contributions to science.

  • We introduce and study “isomonodromy” transformations of the matrix linear difference equation Y (z + 1) = A(z)Y (z) with polynomial A(z). Our main result is construction of an isomonodromy action of Zm(n+1)−1 on the space of coefficients A(z) (here m is the size of matrices and n is the degree of A(z)). The (birational) action of certain rank n subgroups can be described by difference analogs of the classical Schlesinger equations, and we prove that for generic initial conditions these difference Schlesinger equations have a unique solution. ...

  • The lecture notes are organized as follows: Chapter 1 gives a concise overview of the theory of Lebesgue and Stieltjes integration and convergence theorems used repeatedly in this course. For mathematic students, familiar e.g. with the content of Bauer (1996) or Bauer (2001), this chapter can be skipped or used as additional reference . Chapter 2 follows closely F¨ollmer’s approach to Itˆo’s calculus, and is to a large extent based on lectures given by him in Bonn (see Foellmer (1991)). A motivation for this approach is given in Sect. 2.1.

  • The emergence of a new paradigm in science offers vast perspectives for future investigations, as well as providing fresh insight into existing areas of knowledge, discovering hitherto unknown relations between them. We can observe this kind of process in connection with the appearance of the concept of solitons [465].

  • In Memory of Dick and Brian Abstract A group is locally finite if every finite subset generates a finite subgroup. A group of linear transformations is finitary if each element minus the identity is an endomorphism of finite rank. The classification and structure theory for locally finite simple groups splits naturally into two cases—those groups that can be faithfully represented as groups of finitary linear transformations and those groups that are not finitary linear. This paper completes the finitary case.

  • The Board on International Comparative Studies in Education (BICSE) was established by the National Research Council (NRC) in 1988 at the request of the U.S. Department of Education’s National Center for Education Statistics (NCES) and the U.S. National Science Foundation (NSF). Under its initial mandate, the board monitored U.S. participation in large-scale international comparative studies.

  • We prove that a typical interval exchange transformation is either weakly mixing or it is an irrational rotation. We also conclude that a typical translation flow on a typical translation surface of genus g ≥ 2 (with prescribed singularity types) is weakly mixing.

  • Scoring Extended- and Short-Response Items Extended- and short-response items are evaluated according to an established scoring scale, called a rubric, developed from a combination of expectations and a sample of actual student responses. Such rubrics must be particularized by expected work and further developed by examples of student work in developing a guide for scorers. Illinois educators play a substantial role in developing these guides used for the scoring of the short- and extended-response items.

  • (BQ) Ebook Signals, Systems, and Transforms is intended to be used primarily as a text for junior-level students in engineering curricula and for self-study by practicing engineers. It assumed that the reader has had some introduction to signal models, system models, and differ-ential equations (as in, for example, circuits courses and courses in mathematics), and some laboratory work with physical systems.

  • The parametric transformation of acoustic and optical phonons in doped superlattices is theoretically studied by using a set of quantum kinetic equations for the phonons. The analytic expression of parametric transformation coefficient of acoustic and optical phonons in doped superlattices is obtained, that depends non-linear on the concentration of impurities. Numerical computations of theoretical results and graph are performed for GaAs:Si/GaAs:Be doped superlattices

  • In this paper we investigate and build up three methods for transforming sequential processes of a net system into concurrent ones. These methods are based on: trace languages, shiftleft and case graphs. They are also presented by detail algorithms and can be applied to other models of concurrent systems. Keywords: net system, reliance alphabet, trace language, maximal concurrent steps, case graph. 1. Introduction The behaviour of a system often is represented by the set of the system’s processes. ...
