Towards Combining Dense Linear Order with Random Graph

Jiamou Liu, Ting Zhang



Abstract


In this paper we present our work in progress towards obtaining a Nelson-Oppen style combination for combining quantified theories, where each individual component theory admits quantifier elimination. We introduces the notion of good model for union theories, for which there exists a simple quantifier elimination scheme that uses the elimination procedures for individual component theories as black boxes. We show that a good model exists for the union theory of dense linear order and random graph, and it coincides with the Fraisse limit of the class of finite graph with ordered vertices.
