Introduction
The mechanization of many verification tasks relies on efficient implementations of decision procedures for fragments of first-order logic. Interactive theorem provers like pvs also make use of such decision procedures to increase the level of automation. Our tool lira3 implements decision procedures based on automata-theoretic techniques for first-order logics with linear arithmetic, namely, for FO(N, +), FO(Z, +,
