... trees are equipped with increasing labellings. Thus we are considering simple families of increasing trees,which are introduced in [1]. Several important tree families, in particular recursive ... of increasing trees can be constructed from simply generated tree families, if one considers for every tree of size n all its increasing labellings, i. e. labellings of the nodes by distinct int...
