Abstract: For the Orlicz sequence spaces generated by a $N$-function
and equipped with the generalized Orlicz norm, criteria of extreme
points and strongly extreme points were presented. Based on the
criterias, both sufficient and necessary conditions were derived to
make these spaces be convex and mid-point locally uniform convex.

Key words: extreme point, strongly extreme point, Orlicz sequence spac, generalized Orlicz norm, extreme point, strongly extreme point, Orlicz sequence spac
