Increasing quasiconcave co-radiant functions with applications in mathematical economics

Martínez-Legaz, Juan Enrique; Rubinov, Alexander M.; … - In: Mathematical Methods of Operations Research 61 (2005) 2, pp. 261-280

We study increasing quasiconcave functions which are co-radiant. Such functions have frequently been employed in microeconomic analysis. The study is carried out in the contemporary framework of abstract convexity and abstract concavity. Various properties of these functions are derived. In...

of quasiconvex functions. In this paper we restrict our attention to quasiconvex radiant functions, i.e. those whose … radiant functions if and only if it is radiant. Our study is carried out in the framework of Abstract Convex Analysis: the … main tool is the description of a supremal generator of the set of radiant functions, i.e. a class of elementary functions …
