Planar rational compacta and universality
We prove that in some families of planar rational compacta there are no universal elements.
Planar rational compacta
In this paper we consider rational subspaces of the plane. A rational space is a space which has a basis of open sets with countable boundaries. In the special case where the boundaries are finite, the space is called rim-finite.
