isIsomorphic -- tests whether two Lie algebra are isomorphic

Description

i1 : g=simpleLieAlgebra("D",4)

o1 = g

o1 : simple LieAlgebra
i2 : h=subLieAlgebra(g,{2,{1,0,1,1}})

o2 = h

o2 : simple LieAlgebra, subalgebra of g
i3 : isIsomorphic(h,simpleLieAlgebra("G",2))

o3 = true

Ways to use isIsomorphic:

  • isIsomorphic(LieAlgebra,LieAlgebra)
  • isIsomorphic(Matrix,Matrix) -- see isIsomorphic -- probabilistic test for isomorphism of modules
  • isIsomorphic(Module,Module) -- see isIsomorphic -- probabilistic test for isomorphism of modules
  • isIsomorphic(LieAlgebraModule,LieAlgebraModule) (missing documentation)

For the programmer

The object isIsomorphic is a method function with options.
