The criteria of strict monotonicity and rotundity points in generalized Calderón–Lozanovskiǐ spaces Original Research Article

In this paper, some basic properties of the general modular space are proven. Criteria for strictly monotone points, extreme points and SUSU-points in generalized Calderón–Lozanovskiǐ spaces are obtained. Consequently, the sufficient and necessary conditions for the rotundity properties of such spaces are given.
