The non-linear Nambu-Goto equation satisfied by the average o f the embedding coordinates of the junction emerges directly from the junc tion conditions along with the rigid deformations and corrections due to t he tension. Therefore\, the equivalence principle generalizes non-triviall y to the string. Our results are valid both in three-dimensional flat and AdS spacetimes. In the context of AdS$_3$/CFT$_2$ correspondence\, our set up could be used to describe a class of interfaces in the conformal field theory featuring relative time reparametrization at the interface which en codes the solution of the Nambu-Goto equation corresponding to the bulk ju nction.\n\nBased on 2404.02149 (accepted for publication in JHEP)\n LOCATION:https://researchseminars.org/talk/NKUA-HEP/27/ END:VEVENT END:VCALENDAR
