We analyze superselection sectors, non-invertible symmetries and selection rules for RG flows triggered via perturbations of a UV two-dimensional conformal field theory (CFT$_2$). To this end we describe a method whose input is the local data, and whose output is the set of submodels of the modular invariant completions. We explain how this output set provides a classification of superselection sectors (DHR categories and Q-systems) and of topological defect lines, leading to a unified and potentially complete approach to selection rules for RG flows. This method is applied to scenarios in which the UV is a coset or a parafermion model. For these CFT$_2$ we explicitly find all submodels of the diagonal modular invariants. Our results gives selection rules that unify several known facts about such RG flows, while also allowing us to find new aspects.

Symmetry TFTs and Anomalies of Non-Invertible Symmetries
已知可逆整体对称性的t Hooft反常可以用高维可逆TQFT来刻画。对于不可逆对称，类似的陈述还有待理解。在这篇文章中，我们讨论了如何在一个不可逆的TQFT称为对称TFT（对称TFT）的链接不变量可以被用来作为一个诊断的不可逆对称的特胡夫特异常。当不可逆对称是非本质不可逆的，因此SymTFT是Dijkgraaf-Witten模型时，可以显式计算连接不变量。我们通过2d阿贝尔Higgs模型和4d伴随QCD和$\mathcal{N}=4$ super Yang-Mills模型的例子来说明这个建议。我们还评论如何不可逆对称性的特胡夫特异常施加新的约束的动态。
