In this contribution to the proceedings, we focus on line defects in 2dQFT and we point out that topological defects naturally embed into a larger class, namely, translation invariant defects. The latter still allow for nonsingular fusion and one obtains a monoidal category of translation invariant defects which contains that of topological defects as a full subcategory. We give a simple perturbative description of translation invariant defects in a perturbed conformal field theory via chiral three-dimensional topological field theory. We show in the example of the Ising CFT and the Lee–Yang CFT that even if no topological defects survive the deformation, some translation invariant defects still do. 000645036 536__ $$0G:(GEPRIS)390833306$$aDFG project G:(GEPRIS)390833306 - EXC 2121: Das Quantisierte Universum II (390833306)$$c390833306$$x0 000645036 536__ $$0G:(GEPRIS)506632645$$aDFG project G:(GEPRIS)506632645 - SFB 1624: Höhere Strukturen, Modulräume und Integrabilität (506632645)$$c506632645$$x1 000645036 536__ $$0G:(DE-HGF)POF4-611$$a611 - Fundamental Particles and Forces (POF4-611)$$cPOF4-611$$fPOF IV$$x2 000645036 588__ $$aDataset connected to CrossRef, Journals: bib-pubdb1.desy.de 000645036 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000645036 7001_ $$00000-0002-0496-3096$$aRunkel, Ingo$$b1$$eCorresponding author 000645036 7001_ $$00000-0002-9066-2838$$aM.
