For the Grassmannian case, the defect is described by Backlund transformation which is responsible for preserving the integrability of the model. We then propose an extension of the Backlund transformation for the Bosonic Thirring model which is verified by some Backlund transitions like vacuum-one soliton, one soliton-one soliton, one soliton-two solitons and two solitons-two solitons. The Lax formulation within the space split by the defect leads to the integrability of Bosonic Thirring model with jump defects.21engSolitons Monopoles and InstantonsIntegrable Field TheoriesArtigo10.1007/JHEP02(2011)017WOS:000287939400043Acesso restrito92877760781495518215976645016606
