GradedLieAlgebras :: lieAlgebra(...,LastWeightHomological=>...)

lieAlgebra(...,LastWeightHomological=>...) -- optional argument for lieAlgebra

Synopsis

Description

This is an option, which tells lieAlgebra to consider the last weight of a generator as the homological degree, if the option is given the value true. Default value is false.

i1 : describe lieAlgebra({a,b},Weights=>{{2,1},{3,2}})

o1 = generators => {a, b}
     Weights => {{2, 1, 0}, {3, 2, 0}}
     Signs => {0, 0}
     ideal => {}
     ambient => LieAlgebra{...10...}
     diff => {}
     Field => QQ
     computedDegree => 0
i2 : describe lieAlgebra({a,b},Weights=>{{2,1},{3,2}},
                 LastWeightHomological=>true)

o2 = generators => {a, b}
     Weights => {{2, 1}, {3, 2}}
     Signs => {0, 0}
     ideal => {}
     ambient => LieAlgebra{...10...}
     diff => {}
     Field => QQ
     computedDegree => 0
