Elizalde, E. (Emili), 1950-2010-05-062010-05-0619790556-2821https://hdl.handle.net/2445/12414Several SL(3,C) self-dual instanton solutions of the Yang-Mills equations are presented which have very striking properties. While one of them is regular and SU(3) inside (outside) a sphere of arbitrarily large (small) radius, another one has all the characteristics of a meron solution (in particular its topological charge is concentrated at one point) although its Pontryagin number equals one. Their continuation to Minkowski space is also studied.4 p.application/pdfeng(c) The American Physical Society, 1979Electrodinàmica quànticaQuantum electrodynamicsinfo:eu-repo/semantics/article10141info:eu-repo/semantics/openAccess
