... version of [Kracht, 1993]. 1.2 Relevance of Command Relations The idea to study the formal properties of command relations is due to [Barker and Pullum, 1990]. There we find a definition of command ... of sub- formulas of ~ and Sf(e) the set of subformulas of ¢. Put S = {f~(x)l 0 E Sf(~) U Sf(e)}. S is certainly finite and its cardinality is bounded by the sum...
