Résumé

We design a $O (n^{3})$ polynomial time algorithm for finding a $(k - 1)$ - regular subgraph in a $k$ -regular graph without any induced star $K_{1, 3}$ (claw-free). A polynomial time algorithm for finding a cubic subgraph in a 4-regular locally connected graph is also given. A family of $k$ -regular graphs with an induced star $K_{1, 3}$ $(k e v e n, k \geq 6)$ , not containing any $(k - 1)$ -regular subgraph is also constructed.
