https://doi.org/10.1007/978-3-662-58125-4Since the pioneering work of D. Bernoulli, J. d’Alembert, L. Euler, J. Fourier and later on of S. D. Poisson, Ch. Sturm and J. Liouville, the theory of Sturm-Liouville problems is an integral part of the professional preparation of mathematicians, physicists and engineers, and at the same time an important and actively developing research field.
