Let $ V$ be a braided tensor category and $ C$ a tensor category equipped with a braided tensor functor $G:Vto Z(C)$. For any exact indecomposable $C$-module category $M$, we explicitly construct a right adjoint of the action functor $rho:Z^V(C)to C^*_{M}$ afforded by $M$. Here $Z^V(C)$ is the M"uger's centralizer of the subcategory $G(V)$ inside the center $Z^V(C)$, also known as the relative center. The construction is parallel to the one presented by K. Shimizu, but using instead the relative coend end. This adjunction turns out to be monadic, thus inducing Hopf monads $T_{V}: Cto C$, such that there is a monoidal equivalence of categories $ C_{T_{V}}simeq Z^V(C).$ If $bar{rho}: C^*_{ M}to Z^V(C)$ is the right adjoint of $rho,$ then $bar{rho}(Id_{M})$ is the braided commutative algebra constructed in [R. Laugwitz and C. Walton. Braided commutative algebras over quantized enveloping algebras, Transform. Groups 26(3) (2021), 957--993]. As a consequence of our construction of these algebras, in terms of the right adjoint to $rho$, we can provide a recipe to compute them when $C=Rep(H# T)$ is the category of finite-dimensional representations of a finite-dimensional Hopf algebra $H# T$ obtained by bosonization, and choosing an arbitrary $Rep(H# T)$-module category $M$. We show an explicit example in the case of Taft algebras.

Any choice of a spherical fusion category defines an invariant of oriented closed 3-manifolds, which is computed by choosing a triangulation of the manifold and considering a state sum model that assigns a 6j symbol to every tetrahedron in this triangulation. This approach has been generalized to oriented closed 3-manifolds with defect data by Meusburger. In a recent paper, she constructed a family of invariants for such manifolds parametrised by the choice of certain spherical fusion categories, bimodule categories, finite bimodule functors and module natural transformations. Meusburger defined generalised 6j symbols for these objects, and introduces a state sum model that assigns a generalised 6j symbol to every tetrahedron in the triangulation of a manifold with defect data, where the type of 6j symbol used depends on what defect data occur within the tetrahedron. The present work provides non-trivial examples of suitable bimodule categories, bimodule functors and module natural transformation, all over categories of $G$-graded vector spaces. Our main result is the description of module functors in terms of matrices, which allows us to classify these functors when $G$ is a finite cyclic group. Furthermore, we calculate the generalised 6j symbols for categories of $G$-graded vector spaces, (bi-)module categories over such categories and (bi-)module functors.

We construct a quantum Frobenius map for the $SL_3$ skein module of any oriented 3-manifold specialized at a root of unity, and describe the map by way of threading certain polynomials along links. The homomorphism is a higher rank version of the Chebyshev-Frobenius homomorphism of Bonahon-Wong. The strategy builds on a previous construction of the Frobenius map for $SL_3$ skein algebras of punctured surfaces, using the Frobenius map of Parshall-Wang for the quantum group $mathcal{O}_q(SL_3).$

This is the second part of a project aimed at formalizing Rozansky-Witten models in the functorial field theory framework. In the first part we constructed a symmetric monoidal $(infty, 3)$-category $mathscr{CRW}$ of commutative Rozansky-Witten models with the goal of approximating the $3$-category of Kapustin and Rozansky. In this paper we extend work of Brunner, Carqueville, Fragkos, and Roggenkamp on the affine Rozansky-Witten models: we exhibit a functor connecting their $2$-category of matrix factorizations with the homotopy $2$-category of $mathscr{CRW}$, and calculate the associated TFTs.

We explicitly construct a (unitary) $mathbb{Z}/2mathbb{Z}$ permutation gauging of a (unitary) modular category $mathcal{C}$. In particular, the formula for the modular data of the gauged theory is provided in terms of modular data of $mathcal{C}$, which provides positive evidence of the reconstruction program. Moreover as a direct consequence, the formula for the fusion rules is derived, generalizing the results of Edie-Michell-Jones-Plavnik. Our construction explicitly shows the genus-$0$ data of the gauged theory contains higher genus data of the original theory. As applications, we obtain an identity for the modular data that does not come from modular group relations, and we prove that representations of the symmetric mapping class group (associated to closed surfaces) coming from weakly group theoretical modular categories have finite images.

We solve the problem of how to classify the first-order vertex-algebraic deformations for any grading-restricted vertex algebra $V$ that is freely generated by homogeneous elements of positive weights. We approach by computing the second cohomology $H^2_{1/2}(V, V)$ constructed by Yi-Zhi Huang. We start with the cocycle on two generators and show that its cohomology class is completely determined by its singular part. To extend the cocycle to any pair of elements in $V$, we take a generating function approach, formulate the cocycle equation, and show that all the complementary solutions are coboundaries. Then we use a very general procedure to construct a particular solution. The procedure applies to vertex algebras that are not freely generated. As a by-product, we show that $H^2_{1/2}(V, V) = H^2_infty(V, V)$. Using these results, we explicitly determine the first-order deformations of the universal Virasoro VOA $Vir_c$, universal affine VOA $V^l(mathfrak{g})$, Heisenberg VOA $V^l(mathfrak{h})$, and the universal Zamolodchikov VOA $W_3^c$.

In this paper we discuss gauging noninvertible zero-form symmetries in two dimensions, extending our previous work. Specifically, in this work we discuss more general gauged noninvertible symmetries in which the noninvertible symmetry is not multiplicity free, and discuss the case of Rep$(A_4)$ in detail. We realize Rep$(A_4)$ gaugings for the $c = 1$ CFT at the exceptional point in the moduli space and find new self-duality under gauging a certain non-group algebra object, leading to a larger noninvertible symmetry Rep$(SL(2, Z_3))$. We also discuss more general examples of decomposition in two-dimensional gauge theories with trivially-acting gauged noninvertible symmetries.

In this work we study the analogues of R-matrices that arise in 5d non-commutative topological-holomorphic Chern-Simons theory, which is known to describe twisted M-theory. We first study the intersections of line and surface operators in 5d Chern-Simons theory, which correspond to M2- and M5-branes, respectively. A Feynman diagram computation of the correlation function of this configuration furnishes an expression reminiscent of an R-matrix derivable from 4d Chern-Simons theory. We explain how this object is related to a Miura operator that is known to realize (matrix-extended) $W_{infty}$-algebras. For 5d Chern-Simons theory with nonabelian gauge group, we then perform a Feynman diagram computation of coproducts for deformed double current algebras and matrix-extended $W_{infty}$-algebras from fusions of M2-branes, M5-branes, and M2-M5 intersections.
