Triangular Lie algebra

Triangular module

Let be a triangular Lie algebra over and be a linear form. The triangular module is the induced -module #m/def/lie

where the vacuum space is the nonzero -module defined by¹

for . This is a direct generalization of the Heisenberg module .

Properties

• Contravariant form on a triangular module
