Higman showed that if A is any language then SUBSEQ(A) is regular, where SUBSEQ(A) is the language of all subsequences of strings in A. We consider the following inductive inferenc...
Abstract. We consider linear time temporal logic enriched with semiextended regular expressions through various operators that have been proposed in the literature, in particular i...
This paper investigates the word problem for inverse monoids generated by a set Γ subject to relations of the form e = f, where e and f are both idempotents in the free inverse m...
We show that if a self-reducible set has polynomial-size circuits, then it is low for the probabilistic class ZPP(NP). As a consequence we get a deeper collapse of the polynomial-...
The sequence selected from a sequence R(0)R(1) . . . by a language L is the subsequence of R that contains exactly the bits R(n + 1) such that the prefix R(0) . . . R(n) is in L. B...
