Generalized DOL trees
Infinite unlabeled trees having a finite number of different subtrees (also called infinite regular trees) arise in a natural way from a DOL system which also gives a natural labeling for the tree. A much more compact representation for the tree often results from a DOL system with fragmentation.
Keywords: formal languages, DOL system, fragmentation, tree labeling.
