Coherence in Three-Dimensional Category Theory

Book Description

Coherence in Three-Dimensional Category (Cambridge Tracts in )
Dimension three is an important test-bed for hypotheses in higher category theory and occupies something of a unique position in the categorical . At the heart of matters is the coherence theorem, of which this book provides a definitive treatment, as well as covering related results. Along the way the author treats such material as the Gray tensor product and gives a of the fundamental 3-groupoid of a space. The book serves as a comprehensive introduction, covering essential material for any student of coherence and assuming only a basic understanding of higher category theory. It is also a reference point for many key concepts in the field and therefore a vital resource for researchers wishing to apply higher categories or coherence results in fields such as topology or theoretical science.
