No return to convexity

Approximate Convexity and Submonotonicity in Locally Convex Spaces

The convexity of the integral operator on the class of the integral operator on the class B(mu,alpha)

In this paper, we study the convexity of the integral operator

The Karush-Kuhn-Tucker Test of Convexity of Univariate Observations and Certain Economic Applications

The problem of convexity runs deeply in economic theory. For example, increasing returns or upward slopes (convexity) and diminishing returns or downward slopes (concavity) of certain supply, demand, production and utility relations are often assumed in economics. Quite frequently, however, the observations have lost convexity (or concavity) due to errors of the measuring process. We derive the...
