Free Associative Algebras
Two-sided ideals
Types
The OSCAR type for two-sided ideals in a free associative algebra is FreeAssAlgIdeal{T}, where T is the element type of the algebra.
Constructors
ideal(R::FreeAssAlgebra, g::Vector{T}) where T <: FreeAssAlgElem
ideal(g::Vector{T}) where T <: FreeAssAlgElemIdeal Membership
ideal_membership — Methodideal_membership(a::FreeAssAlgElem, I::FreeAssAlgIdeal, deg_bound::Int)Return true if calculations with intermediate degrees bounded by deg_bound prove that $a$ is in $I$. Otherwise, a return of false indicates an inconclusive answer, but larger deg_bounds give more confidence in a negative answer.
