Bicat is not triequivalent to Gray

Stephen Lack

Bicat is the tricategory of bicategories, homomorphisms, pseudonatural transformations, and modifications. Gray is the subtricategory of 2-categories, 2-functors, pseudonatural transformations, and modifications. We show that these two tricategories are not triequivalent.

Keywords: bicategory, tricategory, Gray-category, coherence
