A Lie algebra multiplier parallels the idea of group theory’s Schur
multiplier. This paper classifies the Lie algebra multipliers for all Lie algebras
in the lower central series of strictly upper triangular matrices. Multipliers are
central, so the classification is focused on computing their dimensions. The
calculations are lengthy because balancing various matrix positions plays an
important role in determining these dimensions. The result divides into six
cases and the dimensions are given as polynomials in the size of the matrices
and the position in the lower central series.
