    We study non-invertible defects in two-dimensionalSNorbifold CFTs. We construct universal defects which do not depend on the details of the seed CFT and hence exist in any orbifold CFT. Additionally, we investigate non-universal defects arising from the topological defects of the seed CFT. We argue that there exist universal defects that are non-trivial in the large-Nlimit, making them relevant for the AdS3/CFT2correspondence. We then focus on AdS3×S3×$$ {\mathcal{M}}_4 $$ M 4 with one unit of NS-NS flux and propose an explicit realization of these defects on the worldsheet.

    A<sc>bstract</sc> In this brief note we calculate the entanglement entropy inM⊗N/SNsymmetric orbifold CFTs in the presence of topological defects, which were recently constructed in [1, 2]. We consider both universal defects which realizeRep(SN) non-invertible symmetry and non-universal defects. We calculate the sub-leading defect entropy/g-factor for defects at the boundary of the entangling surface as well as inside it.

    A<sc>bstract</sc> We consider the uplift of co-dimension two defect solutions of seven dimensional gauged supergravity to eleven dimensions, previously found by two of the authors. The uplifted solutions are expressed as Lin-Lunin-Maldacena solutions and an infinite family of regular solutions describing holographic defects is found using the electrostatic formulation of LLM solutions.
