| Resumen: | The notion of ball proximinality and the strong ball proximinality were recently introduced in [2]. We prove that a closed * subalgebra 饾挏 of 饾櫜(饾殌) is strongly ball proximinal in 饾櫜(饾殌) and the metric projection from 饾櫜(饾殌), onto the closed unit ball of 饾挏, is Hausdorff庐 metric continuous and hence has continuous selection. |
