Resumo(s)
Let H be a pseudovariety of
abelian groups corresponding to a recursive supernatural number.
In this note we explain how a concrete implementation of an algorithm to
compute the kernel of a finite monoid relative to H can be achieved.
The case of the pseudovariety Ab of all finite abelian groups was
already treated by the second author and plays an important role here, where we
will be interested in the proper subpseudovarieties of Ab. Our work
relies on an algorithm obtained by Steinberg.
