GradedLieAlgebras :: intersectionLie

intersectionLie -- computes a basis for the intersection of subspaces of a given degree

Synopsis

Description

This is just linear algebra in the specified degree

i1 : L = lieAlgebra{a,b,c}

o1 = L

o1 : LieAlgebra
i2 : intersectionLie(2,{{2 a b + a c + 2 b c, a b + b c},{- a b + a c + b c, a c + b c},{a b + a c - b c, a b + a c}})

o2 = {(b a) + (c a) + (c b)}
