The book provides the latest research results on measuring Credit Rating Migration by mathematical methods. It brings about most popular mathematical models, methods and applications on this area, especially presents the latest development on structure models. It is systematically collects the models, methods and results in this area.The book first introduced the financial background and preliminary mathematical theory. Then two mainstream mathematical models for measuring default risks, the reduced form model and structure model, are presented. The structure model for measuring credit rating migration risks is the main part of the book and authors prove the existence, uniqueness, regularities, asymptotic behavior, traveling wave and other properties of the solutions of the model. The structural credit rating migration model is also extended to more general case, such as stochastic interest rate, multiple ratings, region switch and so on. Some credit derivatives, and numerical analysis, parameter calibration and estimate of the migration boundary of the models are given in the last two chapters.The book focuses on theoretical financial investigators, especially financial mathematical researchers and students. The book is involved various mathematical models, such as PDE, numerical simulation etc., some of them are interesting mathematical problems, so that, and a good reference book to study mathematical modeling in credit rating migration. It might also be used as a textbook for students in financial credit risks.

This Element conceptualises translation reception as a form of cultural negotiation in which cognitive processes and sociocultural factors converge to form understanding. Drawing on empirical examples from a variety of translational phenomena, it maps a range of methodologies, including surveys, interviews, eye-tracking experiments, and big data analytics, to examine how heterogeneous reader expectations are either reconciled or divided. This Element argues that the ambiguities surrounding readers' identities and behaviours exemplify how reception thrives on paradoxes, uncertainties, and fluid boundaries. It proposes a nonlinear trade-off model to emphasise that mutual benefits in high-stakes communication can only be achieved when a requisite degree of trust is maintained among all stakeholders. This trust-based approach to translation reception provides us with the epistemological and methodological tools to navigate our post-truth multilingual world, where a new technocratic order looms. This title is also available as Open Access on Cambridge Core.

There is an enormous amount of work in the literature about the blow-up behavior of evolution equations. It is our intention to introduce the theory by emphasizing the methods while seeking to avoid massive technical computations. To reach this goal, we use the simplest equation to illustrate the methods; these methods very often apply to more general equations.
