It has been open for years to clarify the relationship between two smooth 4-manifolds invariants, the shadow model (motivated by statistical mechanics [Tur91]) and the simplicial Crane-Yetter model (motivated by topological quantum field theory [CY93]), both of which degenerate to the 3D Witten-ReshetikhinTuraev model in a special case. Despite the seeming difference in their origins and formal constructions, we show that they are in fact equal. Along the way, we sketch a dictionary between the…

Observables in the Turaev-Viro and Crane-Yetter models

We define an invariant of graphs embedded in a 3-manifold and a partition function for 2-complexes embedded in a triangulated 4-manifold by specifying the values of variables in the Turaev-Viro and

On the Category of Boundary Values in the Extended Crane-Yetter TQFT

The Crane-Yetter state sum is an invariant of closed 4-manifolds, defined in terms of a triangulation, based on 15-j symbols associated to the category A of representations over quantum sl2 (at a

Factorization homology and 4D TQFT

In [BK], it is shown that the Turaev-Viro invariants defined for a spherical fusion category $\mathcal{A}$ extends to invariants of 3-manifolds with corners. In [Kir], an equivalent formulation for

A CATEGORICAL CONSTRUCTION OF 4D TOPOLOGICAL QUANTUM FIELD THEORIES

In recent years, it has been discovered that invariants of three dimensional topological objects, such as links and three dimensional manifolds, can be constructed from various tools of mathematical

Quantum Invariants of Knots and 3-Manifolds

This monograph, now in its second revised edition, provides a systematic treatment of topological quantum field theories in three dimensions, inspired by the discovery of the Jones polynomial of

Categorical Center of Higher Genera and 4D Factorization Homology

Many quantum invariants of knots and 3-manifolds (e.g. Jones polynomials) are special cases of the Witten-Reshetikhin-Turaev 3D TQFT. The latter is in turn a part of a larger theory the Crane-Yetter

Integrating quantum groups over surfaces

We apply the mechanism of factorization homology to construct and compute category‐valued two‐dimensional topological field theories associated to braided tensor categories, generalizing the

Evaluating TQFT invariants from G-crossed braided spherical fusion categories via Kirby diagrams with 3-handles

A family of TQFTs parametrised by G-crossed braided spherical fusion categories has been defined recently as a state sum model and as a Hamiltonian lattice model. Concrete calculations of the

Semisimple 4-dimensional topological field theories cannot detect exotic smooth structure

We prove that semisimple 4-dimensional oriented topological field theories lead to stable diffeomorphism invariants and can therefore not distinguish homeomorphic closed oriented smooth 4-manifolds

Turaev-Viro invariants as an extended TQFT

In this paper, we present the next step in the proof that $Z_{TV,\C} = Z_{RT, Z(\C)}$, namely that the theories give the same 3-manifold invariants. In future papers we will show that this equality
