  Lie algebra in graphical language

Remark on summation convetion:  When an expression has a repeated index, once as a superscript and once as a subscript, the summation over this index is implied, for instance $$A^j_iv^i \equiv \sum_iA^j_iv^i$$  I forgot to mention it at the beginning of the talk.
