Chains, Subwords, and Fillings: Strong Equivalence of Three Definitions of the Bruhat Order
Let Sn be the group of permutations of [n] = {1, . . . , n}. The Bruhat order on Sn is a partial order relation, for which there are several equivalent definitions. Three well-kno...

Component Substitutability via Equivalencies of Component-Interaction Automata
We provide a new look at formal aspects of component substitutability (replacement of a component with a new one) and independent implementability (reuse of a component in any sys...
