This paper studies the problem of maintaining the 2-edge-connected components of a graph undergoing repeated dynamic modifications, such as edge insertions and edge deletions. It is shown how to test at any time whether two vertices belong to the same 2-edge-connected component, and how to insert and delete an edge in $O(m^{2/3} )$ time in the worst case, where m is the current number of edges in the graph.

Abstract
This paper studies the problem of maintaining the 2-edge-connected components of a graph undergoing repeated dynamic modifications, such as edge insertions and edge deletions. It is shown how to test at any time whether two vertices belong to the same 2-edge-connected component, and how to insert and delete an edge in $O(m^{2/3} )$ time in the worst case, where m is the current number of edges in the graph.
