Popis: | The intersection preserving mapping problem was introduced by Czimmermann in his research on isomorphism of hypergraphs. This paper explores the condition when an intersection preserving mapping is not induced by any bijection. A new characterization of intersection preserving mappings is presented, and a generalization of Whitney’s line graph isomorphism theorem is proved. |
