In this article we discuss lattice convexity and concavity of Calderón-Lozanovskii space Eφ, generated by a quasi-Banach space E and an increasing Orlicz function φ. We give estimations of convexity ...

This is a preview. Log in through your library . Abstract An elementary proof of the normality condition is given. In addition, the convexity-concavity character of the yield surface is found to be ...

Nonparametric estimation under shape constraints represents a vibrant field that bridges rigorous mathematical theory with practical applications. This approach leverages inherent qualitative ...

The concavity exercise asks students to think about erosion in natural forms and how that concavity contrasts with the convexity of the objects. Dominant, subdominant, and subordinate relationships ...
