Let $\Pi^{\natural}\subset \Lambda\otimes\mathbb{R}\subset V^{f\natural}_{tw}$ be a four-dimensional subspace, and let $\mathsf{Top}_{\Pi^{\natural}}$ be the full subcategory of to…

Odd-dimensional gauging conjecture. In $d=2n+1$ dimensions, generalized symmetries are mostly related by gauging to invertible symmetries.

Let $\mathcal{T}$ be a $d$-dimensional theory with a categorical (non-invertible) symmetry $\mathcal{S}$ given by higher-fusion categories. Its SymTFT $\mathfrak{Z}(\mathcal{S})$ i…

Let $M_2$ be a two-dimensional defect, let $D(M_2,b_2',a_1)$ denote the codimension-two defect coupled to background fields $b_2'$ and $a_1$, and let … be a 0-form and a 1-form fie…
