| dc.description.abstract | The time evolution of expanded and contracted solitary waves of the Dirac field with scalar self-interaction is exhibited. It is shown that the positivity of the second variation of the energy functional is not a necessary condition for the stability of these waves as has been recently suggested. | |

Convergence of the numerical methods used in both this Letter and A. Álvarez and B. Carreras, Phys. Lett. 85A, 327 (1981), is proved by A. Álvarez, Kuo Pen-Yu, and L.
