We study deeply critical oriented graphs, those graphs for which the removal of any arc results in a decrease of the oriented chromatic number by 2.

This is usually indicated with an arrow on the edge; more formally, if v and w are vertices, an edge is an unordered pair {v, w}, while a directed edge, called an arc , is an ordered pair (v, w) or (w, v). fish tank tables for cheapWebHire the Best RemoteGraph theory Developerin 72 Hours.
