Equations of Mathematical Diffraction Theory focuses on the comparative analysis and development of efficient analytical methods for solving equations of mathematical diffraction theory. Following an overview of some general properties of integral and differential operators in the context of the linear theory of diffraction processes, the authors provide estimates of the operator norms for various ranges of the wave number variation, and then examine the spectral properties of these operators. They also present a new analytical method for constructing asymptotic solutions of boundary integral equations in mathematical diffraction theory for the high-frequency case.Clearly demonstrating the close connection between heuristic and rigorous methods in mathematical diffraction theory, this valuable book provides you with the differential and integral equations that can easily be used in practical applications.

This volume is concerned mainly with basic problems of the theory of thermoelasticity. Beginning with the basic laws of thermomechanics, there follows a treatment of the theory of thermoelasticity for bodies with initial stress and initial heat flux. Subsequent chapters cover the analysis of linear thermoelastodynamics and equilibrium theory. The authors conclude with a study of nonlinear thermoelasticity. On the whole, the subject matter is directed towards recent developments. The theory of thermoelasticity should be of interest both from the mathematical and the technical points of view, and relevant examples and exercises which illustrate the theory are given throughout the text. The book should be of interest to mathematicians, physicists and specialists working in the fields of thermoelasticity, elasticity, civil engineering and geophysics.

This book presents cutting-edge methodologies, including AI techniques, for corporate credit analysis as developed for the in-house credit assessment system (ICAS) of Banca d’Italia. The first part illustrates the methods, applications and use cases of the existing system, that is employed to evaluate a large sample of Italian non-financial companies. The second part presents the rating systems in use at commercial banks and provides a benchmarking exercise of the latter systems against the ratings produced by ICAS. The third part presents new developments of the system, including the evaluation of climate transition risk, climate physical risk, social and governance factors, cyber risk, sentiment analysis. The book illustrates all state-of-the-art AI applications developed for ICAS, providing practical examples and empirical results.
