Abstract
Let G be a connected graph, S be a subset of edges in G, and k be a positive integer. If \(G-S\) is disconnected and every component has at least k vertices, then S is a k-extra edge-cut of G. The k-extra edge-connectivity, denoted by \(\lambda _{k}(G)\), is the minimum cardinality over all k-extra edge-cuts of G. If \(\lambda _{k}(G)\) exists and at least one component of \(G-S\) contains exactly k vertices for any minimum k-extra edge-cut S, then G is super-\(\lambda _{k}\). Moreover, when G is super-\(\lambda _{k}\), the persistence of G, denoted by \(\rho _k(G)\), is the maximum integer m for which \(G-F\) is still super-\(\lambda _{k}\) for any set \(F\subseteq E(G)\) with \(|F|\le m\). It has been shown that the bounds of \(\rho _k(G)\) when \(k\in \{1,2\}\). This study shows the bounds of \(\rho _k(G)\) when \(k\ge 3\).
