It is shown that every strongly lattice norm on $c_0(\Gamma)$ can be approximated by $C^\infty$ smooth norms. We also show that there is no lattice and G\^ateaux differentiable norm on $C_0[0,\omega_1]$.
Classification : 46B03, 46B20, 46B26
Keywords: smooth norms; approximation; lattice norms; $c_0(\Gamma)$; $C_0[0, \omega_1]$
