## Abstract Using a suitable orientation, we give a short proof of a strengthening of a result of Czumaj and Strothmann 4: Every 2‐edge‐connected graph __G__ contains a spanning tree __T__ with the property that $d\_T(v)\le {d\_T(v)+\,3 \over 2}$ for every vertex __v__. As an analogue of this resul

The problem of finding a minimum weight k-vertex connected spanning sub-Ε½ . graph in a graph G s V, E is considered. For k G 2, this problem is known to be NP-hard. Based on the paper of Auletta, Dinitz, Nutov, and Parente in this issue, Γ„ 4 we derive a 3-approximation algorithm for k g 4, 5 . This

The problem of finding a minimum weight k-vertex connected spanning sub-Ε½ . graph in a graph G s V, E is considered. For k G 2, this problem is known to be NP-hard. Combining properties of inclusion-minimal k-vertex connected graphs Ε½ and of k-out-connected graphs i.e., graphs which contain a vertex
