| contents | We study the arbitrariness of boundary conditions (BCs) on $S^1/Z_2$ brane-world models with the gauge group $U(N)$. The BCs are chosen independently on the branes and the bulk in this model. There are numerous choices for BCs in general, but some of the BCs are connected through gauge transformations. We show that the equivalent relations are obtained on the UV-brane without relying on specific transformation parameters. There is no other equivalent relation on the UV-brane. On the other hand, we find that a gauge transformation with a kink connects all the BCs on the bulk and IR-brane. It means that the arbitrariness of BCs is completely solved on the bulk and the IR-brane except for the UV-brane. |
