Thick tangles, 2-tangles is a free semistrict . monoidal 2-category with duals on one unframed self-dual object. Very similar geometric 2-categories appear in the theory of knotted surfaces in 4-dim space as developed by Carter, Saito, Fischer, and others, see for example [.], [.], and [.].

Isomorphism between Tangle and Cobordism Double Categories,phic as double categories. This provides us with a systematic combinatorial presentation of 3-manifolds with comers that respects the two gluing operations. The main result of the first three chapters of this book is summarized in the following presentation theorem.

Isomorphism between Tangle and Cobordism Double Categories,ther is the double category of equivalence classes of admissible tangles . from Chapter 2. The purpose of this chapter is to show that they are isomorphic as double categories.

Monoidal categories and monoidal 2-categories,particular, we will review braided abelian tensor categories (BTQ, the properties of Hopf algebras in such BTC’s, as well as the construction of a symmetric monoidal 2-category of abelian categories. Our discussion will also include a number of new lemmas that will significantly simplify the proof o
