Abstract
Hilbert spaces have two levels of equivalence; linear isomorphism and unitary isomorphism. The fact that 2-Hilbert spaces have three levels gives 2-Hilb the structure of a higher dagger category. This provides extra structure to the category of topological line operators in unitary theories, generalizing the fact that point operators form a C*-algebra.
