Attributes to vectors

[jcguu95]

Is it possible to add attributes to vectors, as elements in a representation of a quantum group? For example, it is convenient if I can assign weights for vectors in a representation.

Hello, yes, this ould be possible. However, the addition function for vectors would have to take that into account: the sum of vectors of the same weight is a weight vector, if the vectors have different weights, then the sum is not a weight vector. All the best, Willem de Graaf
