[en] A detailed analysis of the quantization of the breathing mode in the Skyrme model is presented. It is shown that breathing strongly affects the behavior of the chiral angle of the hedgehog-like soliton. 7 refs

[en] Tony Hilton Royle Skyrme was born on 5 December 1922 at 7 Blessington Road, Lewisham (Kent), London. Tony's maternal grandfather was Herbert William Thomson Roberts, a tidal computer for the Admiralty by profession. The inclusion of Lord Kelvin's baptismal name (William Thomson) among his forenames reflects the professional contact which Tony's great-grandfather had with Lord Kelvin and the high regard in which he held the latter. This great-grandfather of Tony's on the maternal side was Edward Roberts. He was appointed Secretary to the Tidal Committee of the British Association for the Advancement of Science, being made responsible later for the construction of the first Tidal Predicter, which had been designed by Lord Kelvin. He played a large part in the design and construction of the Universal Tide-predicting Machines used by the Indian and Colonial Government and by the Admiralty Hydrographic Office. It was his house which held the Tidal Predicter, the first model of the machine, which made such a strong impression on the young Tony and influenced so greatly the development of his later ideas, as Tony himself recounted in a lecture given at a Workshop on Skyrmions in 1984

[en] We present a systematic tool for derivation of the Bogomolny equation for the BPS Skyrme model. Furthermore, we find a generalization of the Bogomolny equation to the case corresponding with a non-zero value of the external pressure. The method is based on the concept of strong necessary conditions and can be applied to any Skyrme-like theory. (paper)

[en] A topological lower bound on the Skyrme energy which depends explicitly on the pion mass is derived. This bound coincides with the previously best known bound when the pion mass vanishes, and improves on it whenever the pion mass is non-zero. The new bound can in particular circumstances be saturated. New energy bounds are also derived for the Skyrme model on a compact manifold, for the Faddeev–Skyrme model with a potential term, and for the Aratyn–Ferreira–Zimerman and Nicole models
