Resumen:
This research contains as a main result the proof that every chordalB1-EPG graph is simultaneously in the graph classes VPT and EPT. Inaddition, we describe structures that must be present in any B1-EPG graphwhich does not admit a Helly-B1-EPG representation. In particular, thispaper presents some features of non-trivial families of graphs properly contained in Helly-B1-EPG, namely bipartite, block, cactus and line graphs ofbipartite graphs.
