The Poisson brackets and the classical local conserved charges necessary for integrability are preserved by boundary conditions in correspondence with involutions which commute with $\sigma$. Applied to $SO(3)/SO(2)$, the nonlinear sigma model on $S^2$, these yield the great circles as boundary submanifolds. Applied to $G \times G/G$, they reproduce known results for the principal chiral model en dc.language.iso eng dc.relation.ispartof Physical Letters B dc.rights Open dc.subject hep-th dc.title Classically integrable boundary conditions for symmetric-space sigma models en dc.contributor.institution School of Physics, Astronomy and Mathematics dc.contributor.institution Science & Technology Research Institute dc.description.status Peer reviewed dc.relation.school School of Physics, Astronomy and Mathematics dc.description.versiontype Final Accepted Version dcterms.dateAccepted 2004-05 rioxxterms.version AM rioxxterms.versionofrecord https://doi.org/10.1016/j.physletb.2004.03.037 rioxxterms.type Journal Article/Review herts.preservation.rarelyaccessed true herts.rights.accesstype Open
