String nets for twisted pivotal categories
Introduces a graphical calculus for twisted pivotal categories and proves that associated string net modules on surfaces form an oriented categorified 2-TQFT independent of the Morse function, with analysis of vanishing on the 2-sphere linked to finite tensor categories.
