Equivalently, it is the number of different equivalence relations with exactly k equivalence classes that may be defined on an n element set. It is worth noting that the following identities hold for every positive integer n as well as whenever . The succeeding lemma, together with the general...
Some of the other theories which have been proved decidable by this method are the first-order and second-order monadic predicate calculus (i.e., with only unary predicate constants and variables)3) , the theory of dense ordered sets, the theory of a single equivalence relation, the theory...
We indicate a way of distinguishing between structures, for which, we call two structures distinguishable. Roughly, being distinguishable means that they diff?er in the number of realizations each gives for some formula. Being non-distinguishable turns out to be an interesting equivalence relation ...

(an aggregate of objects) was provided in the 1870’s by G. Cantor. First, Cantor defines the concept of the equivalence of sets. Specifically, two sets are said to be equivalent if the objects of the sets can be put into one-to-one correspondence. Then the number of objects within a...

Because of that disparity, the article demonstrates that we cannot consider an equivalence between the runoff hydrographs for pervious surfaces or low CNs. In addition, the article shows that catchment width and storm depth considerably influence the infiltration process, and thus the equivalency ...
