Elizalde, E. (Emili), 1950-2010-05-062010-05-0619840556-2821https://hdl.handle.net/2445/12427We construct an extensive family of Bose string models, all of them classically equivalent to the Nambu and Eguchi models. The new models involve an arbitrary analytical function f(u), with f(0) = 0, and are based on the Brink-Di Vecchia-Howe and Polyakov string action. The semiclassical approximation of the models is worked out in detail.6 p.application/pdfeng(c) The American Physical Society, 1984TermodinàmicaPartícules (Física nuclear)Teoria de camps (Física)ThermodynamicsParticles (Nuclear physics)Field theory (Physics)info:eu-repo/semantics/article130info:eu-repo/semantics/openAccess
