Recognizing Cartesian graph bundles. (English) Zbl 0876.05094
Graph bundles are extensions of covering graphs and graph products. The authors develop an algorithm that finds a representation as a nontrivial Cartesian graph bundle for all graphs that are Cartesian graph bundles over a triangle-free simple base. The problem of recognizing graph bundles over general base remains open.
