Non-invertible defects from the Conway SCFT to K3 sigma models II: duality and Fibonacci defects
Roberta Angius, Stefano Giaccari, Sarah M. Harrison +1
We continue the study, initiated in [hep-th:2504.18619], of topological defect lines (TDLs) in the Conway module and K3 non-linear sigma models (NLSMs). In the cas…

Non-invertible defects from the Conway SCFT to K3 sigma models I: general results
Roberta Angius, Stefano Giaccari, Sarah M. Harrison +1
We initiate the study of supersymmetry-preserving topological defect lines (TDLs) in the Conway moonshine module . We show that the tensor category of such defects,…

Vertex algebras, topological defects, and Moonshine
Roberto Volpato
We discuss topological defect lines in holomorphic vertex operators algebras and superalgebras, in particular Frenkel-Lepowsky-Meurman Monster VOA with central charge…
