The rapid development of contemporary technology requires ever more extensive mathematical preparation for engineers. This has resulted in a demand for a more complete exposition of the applications of the fundamental mathematical disciplines for engineers, technicians, and students in technological institutions.
The present book examines a number of physical and technical problems which involve second-order partial differential equations. Considerable attention is also given to the theory of such equations. In addition, the text includes several chapters and sections of a general nature (indicated by an asterisk). The material in these sections does not as yet have direct application; nonetheless, it is important for an understanding of contemporary scientific literature on mathematical physics.
