Spontaneous Symmetry Breakdown without Massless Bosons
We examine a simple relativistic theory of two scalar fields, first discussed by Goldstone, in which as a result of spontaneous breakdown of U(1) symmetry one of the scalar bosons is massless, inExpand

Dynamical symmetries in a spherical geometry. I
The two potentials for which a particle moving non-relativistically in a spherical space under the action of conservative central force executes closed orbits are found. When the curvature is zeroExpand

An Application of Perturbation Theory to the F and G Matrix Method of Calculating Molecular Vibration Frequencies
The F and G matrix form of the secular equation for molecular vibrations may be split into two approximate equations, of which one has as its roots the high frequencies (corresponding to relativelyExpand

Quadratic lagrangians and general relativity
SummaryTwo out of the three sets of field equations associated with Lagrangians quadratic in the Riemann-Christoffel tensor, which were recently discussed by Stephenson, are shown to be equivalent toExpand
