Abstract: We show that the monadic second-order quantifier alternation hierarchy over finite directed graphs and over finite two-dimensional grids is infinite. For this purpose we investigate sets of grids where the width is a function in the height. The infiniteness of the hierarchy is then witnessed by n-fold exponential functions for increasing integers n. 1 Introduction The subject of this paper is monadic second-order logic over graphs. In this logic, one can quantify over vertices and sets of... (Update)
