Reuter G.E.H. Elementary differential equations and operators

Routledge, 1964. — 74 p.
The main purpose of this book is to give a thoroughly elementary account of the 'operational method' for solving linear differential equations with constant coefficients, subject to prescribed initial conditions. No previous knowledge of differential equations will be demanded from the reader, and accordingly the basic properties of linear differential equations with constant coefficients are treated in the first chapter. This chapter may be found
useful even by those readers who do not wish to learn the more specialized technique of operators, treated in the second chapter.
The book is addressed primarily to students of the exact sciences and of engineering, but it deals only with mathematical techniques and does not contain any illustrative examples drawn from other fields (such as mechanics, electric circuit theory, probability theory, and so on). Each reader will no
doubt meet problems in his own field of studies to which the mathematical techniques described in this book may usefully be applied.
