Simple Bratteli Diagrams with a Gödel-incomplete C*-equivalence Problem
An abstract simplicial complex is a finite family of subsets of a finite set, closed under subsets. Every abstract simplicial complex C naturally determines a Bratteli diagram and a stable AF-algebra A(C). Consider the following problem: INPUT: a pair of abstract simplicial complexes C and C′; QUESTION: is A(C) isomorphic to A(C′)? We show that this problem is Gödel incomplete, i.e., it is recu...
متن کاملMinimal Bratteli Diagrams and Dimension Groups of Af C-algebras
A method is described which identifies a wide variety of AF algebra dimension groups with groups of continuous functions. Since the continuous functions in these groups have domains which correspond to the set of all infinite paths in what will be called minimal Bratteli diagrams, it becomes possible, in some cases, to analyze the dimension group’s order preserving automorphisms by utilizing th...
متن کاملGeodesic laminations and Bratteli diagrams of AF C*-algebras
Geodesic laminations is a remarkable abstraction (due to W. P. Thurston) of many otherwise unrelated phenomena occurring in differential geometry, complex analysis and geometric topology. In this article we focus on connections of geodesic laminations with the inductive limits of finite-dimensional semi-simple C-algebras (AF C-algebras). Our main result is a bijection between combinatorial pres...
متن کاملCohomology of Ordered Bratteli Diagrams
Given a simple ordered Bratteli diagram, B, with multiple maximal paths and minimal paths, and the Natural Extension system (X; T) generated by this diagram, there is a compact topological graph G which gives the following exact sequence:
متن کاملTiling groupoids and Bratteli diagrams II: structure of the orbit equivalence relation
In this second paper, we study the case of substitution tilings of R. The substitution on tiles induces substitutions on the faces of the tiles of all dimensions j = 0, . . . , d− 1. We reconstruct the tiling’s equivalence relation in a purely combinatorial way using the AF -relations given by the lower dimensional substitutions. We define a Bratteli multi-diagram B which is made of the Brattel...
