Deciding Unambiguity and Sequentiality of Polynomially Ambiguous Min-Plus Automata
Abstract. This paper solves the unambiguity and the sequentiality problem for polynomially ambiguous min-plus automata. This result is proved through a decidable algebraic characte...

Branching Bisimilarity between Finite-State Systems and BPA or Normed BPP Is Polynomial-Time Decidable
In this paper we present polynomial time algorithms deciding branching bisimilarity between finite-state systems and several classes of infinite-state systems: BPA and normed BPP...

Decidability of Sub-theories of Polynomials over a Finite Field
Abstract. Let Fq be a finite field with q elements. We produce an (effective) elimination of quantifiers for the structure of the set of polynomials, Fq[t], of one variable, in...

Deciding the finiteness of the number of simple permutations contained in a wreath-closed class is polynomial
We present an algorithm running in time O(n log n) which decides if a wreathclosed permutation class Av(B) given by its finite basis B contains a finite number of simple permutati...

Efficient and Error-Correcting Data Structures for Membership and Polynomial Evaluation
We construct efficient data structures that are resilient against a constant fraction of adversarial noise. Our model requires that the decoder answers most queries correctly with...
