Yetter, David N![Functorial Knot Theory: Categories of Tangles, Coherence, Categorical Deformations and Topological Invariants](https://support.digitalhusky.com/media/annotations/sorted/656/6568898/CHSBZCOP036568898.jpg)
A study of functorial knot theory. It discusses the key ideas in the discovery of monoidal categories of tangles as central objects in low-dimensional topology. The focus then turns to the deformation theory of monoidal categories and the related deformation theory of monoidal functors.
