Nd-solid varieties

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2007
A non-deterministic hypersubstitution maps any operation symbol of a tree language of type ? to a set of trees of the same type, i.e. to a tree language. Non-deterministic hypersubstitutions can be extended to mappings which map tree languages to tree languages preserving the arities.
