Abstract
Possibility of representation of a value of convexification of functio n at the given point as a convex combination of the values of function (spannability) is studied. Spannability of functions turned out to be important in different fields e.g. in the study of quasi-cores of mon etary economies with nonconvex preferences (mathematical economics), i n the theory of relaxation of variation problems (variational calculus ). Apparently, Shapley and Shubik (Econometrica, 1966, 34, 805-827) we re first to discuss it.
