THE HAUSDORFF DIMENSION OF A GRAPH-DIRECTED SET WHOSE UNDERLYING MULTIGRAPH IS A CARTESIAN PRODUCT OR A TENSOR PRODUCT OF MULTIGRAPHS
Abstract
In this paper, we compute the Hausdorff dimension of a graph-directed set when the underlying multigraph is a Cartesian product or a tensor product of several multigraphs. We give explicit formulas in terms of the eigenvalues of the graph and the similarity ratios used with each graph.
