Traces on ideals in pivotal categories
Published 8 Mar 2011 in math.QA and math.GT | (1103.1660v2)
Abstract: We extend the notion of an ambidextrous trace on an ideal (developed by the first two authors) to the setting of a pivotal category. We show that under some conditions, these traces lead to invariants of colored spherical graphs (and so to modified 6j-symbols).
