抜粋

Structural induction is a technique for proving that a system consisting of many identical components works correctly regardless of the actual number of components it has. Previously the authors have obtained conditions under which structural induction goes through for rings that are modeled as a Petri net satisfying a fairness requirement. The conditions guarantee that for some k, all rings of size k or greater exhibit 'similar' behavior. The key concept is the similarity between rings, where rings Rk and Rl of sizes k and l, respectively, are said to be similar if, intuitively, (1) none of the components in either ring can tell whether it is in Rk or Rl, and (2) none of the components (except possibly one) can tell its position within the ring to which it belongs. A ring satisfying this second property is said to be uniform. In this paper we prove the undecidability of various basic questions regarding similarity and uniformity. Some of the questions shown to be undecidable are: (1) Is there k such that Rk and Rk+1 are similar? (2) Is there k such that all rings of size k or greater are mutually similar? (3) Is there k such that Rk is uniform? (4) Is there k such that Rk, Rk+1, Rk+2,... are all uniform?
