On the metric dimension, the upper dimension and the resolving number of graphs
Delia Garijo, Antonio González, Alberto Márquez
This paper deals with three resolving parameters: the metric dimension, the upper dimension and the resolving number. We first answer a question raised by Chartrand and Zhang askin…
