Finding NIM-reps
In two-dimensional conformal field theory, bulk primary fields obey an operator product algebra following the fusion algebra. Consistent sets of boundary conditions are in correspondence with the Non-negative Integer Matrix representations (NIM-reps) of this fusion algebra. Methods of constructing NIM-reps will be reviewed, as well as their relation to D-brane charges.
