Abstract
An alternative approach to the n-dimensional small oscillations problem is presented. This method is based on the finding of n new independent constants of motion to get the n eigenfrequencies and the n normal coordinates of the problem. These constants of motion exist and may be explicitly constructed for any small oscillations problem. Three examples are presented. One of them involves solving a five-dimensional small oscillations problem whose solution is usually obtained by finding the roots of a quintic algebraic equation. The approach constructed here is especially suited to deal with high-dimensional problems. Applications to small oscillations as well as to high-degree algebraic equation solutions are discussed.
期刊介绍:
The mission of the American Journal of Physics (AJP) is to publish articles on the educational and cultural aspects of physics that are useful, interesting, and accessible to a diverse audience of physics students, educators, and researchers. Our audience generally reads outside their specialties to broaden their understanding of physics and to expand and enhance their pedagogical toolkits at the undergraduate and graduate levels.
