Kapranov-Voevodsky 2-vector space

A Kapranov–Voevodsky 2-vector space is a kind of 2-vector space, in this case a category equivalent to Vect n{}^n for some finite nn. For details, see:

  • Mikhail Kapranov and Vladimir Voevodsky, 2-categories and Zamolodchikov tetrahedra equations, in Algebraic Groups and Their Generalizations: Quantum and Infinite-Dimensional Methods, Proc. Sympos. Pure Math. 56, Part 2, AMS, Providence, RI, 1994, pp. 177–259.

There is also a more abstract characterization of Kapranov–Voevodsky 2-vector spaces, described here:

Namely, they are semisimple kk-linear abelian categories with finitely many simple objects. We may also drop the finiteness condition here to define a class of ‘infinite-dimensional’ Kapranov–Voevodsky 2-vector spaces. For further discussion and more references, see:
