Various notions of the Markov property relative to a partial ordering have been proposed by both physicists and mathematicians. This work develops techniques for stying Markov fields on partially ordered sets. We introduce random transformations of the index set which preserves …
This book introduces the reader to the general theory of partially ordered sets, i.e., posets. The text is presented in a rather informal manner, with interesting examples and computations, which rely on the Hasse diagram to build graphical intuition for the structure of finite …

In this text, we use characters of lattices (i.e. lattice morphisms into the two-element lattice) and characters of topological spaces (i.e. continuous functions into an appropriately topologized two element space) to obtain connections and dualities between various categories o…
