NICK GURSKI THESIS

Timothy Gowers et al, Princeton University Press, Is there any general framework for proving that some classes of diagrams commute in every tricategory? Sign up using Email and Password. Eugenia Cheng’s Research papers The category of opetopes and the category of opetopic sets. However, coherence for monoidal categories can also refer to the following result: Recall Mac Lane’s version of coherence for monoidal categories, which one can state informally as follows:. Has this been covered in the literature?

Submitted book Higher dimensional categories: As braiding are in general not symmetries, some diagrams of gurwki 2-cells in monoidal bicategories do not commute in general.

This is related to the fact that a one-object monoidal bicategory is “morally the same” as a braided monoidal category a result due to Gordon, Power, Streetwith the braiding given by a clever composition of 2-cells.

For example, is the following naive generalization of Mac Lane coherence true? I stumbled upon this type of questions while studying possible definitions of a dual pair of objects in a monoidal bicategory.

The strictifying version of coherence is an important theorem on its own right, but it also implies the simple-minded version of coherence with the following argument. In Journal of Pure and Applied Algebra, 2: Comparing operadic theories of n -category,47 pages. I believe some argument similar in spirit to the one from notes of Tom Leinster should work, but triequivalences or more generally, homomorphisms of tricategories are such complicated objects that it is not quite obvious for me how to do this.
