Hi,
Does anyone know that what is co spanning tree. If there are some good answers then it would be really good to have an example also.
Thanks

The paper here uses this name for the complement of a spanning tree, i.e. the set of edges which do not lie in some given spanning tree. 


If $G = (V, E)$ has a spanning tree $T = (V, E_1)$, the cospanning tree of $T$ is a spanning subgraph of $G$, defined by $(V, EE_1)$.
