This Chelsea publication is now available in English for the general mathematical audience, 50 years after the original Russian edition was published. The book lays the foundation of what later became Krein's Theory of String. The original ideas stemming from mechanical considerations are developed with clarity and the book can be read profitably by both research mathematicians and engineers.
