摘要：

A recent study of phi-4-solitons on a circle is extended to phi-4-bounces and sine-Gordon-solitons. In each case the static solutions are derived. It is then shown that the equations of small fluctuations about these solutions are Lame equations whose discrete, polynomial solutions and eigenvalues are known. Using these, the classical stability of the static solutions can be investigated. Sphalerons and bounces appear as unstable configurations.
