Abstract:The criterion for k-smooth points of the Orlicz sequence space endowed with the Orlicz norm is proved. The necessary and sufficient conditions of k-smoothness of lM and l(M) are obtained, respectively. Finally, we give the counterexamples which show that previous results are not true.
Keywords:Orlicz sequence space  k-smoothness  k-smooth point  Orlicz norm  Luxemburg norm
