Sequências convergentes de estruturas discretas e testabilidade

Abstract

In this work, we studied the recent theory of convergent graph sequences and its extensions to permutation and partially ordered sets with fix dimension. We’ve conjectured a lemma of weak regularity on intervals that, if this conjecture is true, we can extend this theory to ordered graphs, which are graphs such that there is a total order on its vertices. We show some interesting relations on permutation and partially ordered sets with ordered graphs. Then, we obtain another proof to the existence of limit objects for all convergent permutation sequences. We also proved that all hereditary property of either permutation or ordered graph is testable.
