According to the requirements of various theories and application
there are many generalizations of Orlicz spaces.The spaces LM
p equipped with the p-Amemiya norms are the generation of the Orlicz spaces.λ-property and uniformly λ-property are important geometric properties in Orlicz spaces.They have close connections with extreme points and strict convexity.In this paper
we conclude that LM
p(1≤p≤∞) spaces have the λ-property and the necessary and sufficient conditions that LM
