摘要: Given a (closed or open) subset X in R n , which is stable with respect to shifts positive directions, weconsider inequalities u(x) – u(y) ≤c(x,y),x,y ∈ X, and for wide class of functions c on × derive smooth solution these inequal ities from Lebesgue measurable one. Applications are given best approximation problem several problems mathematical economics relating preferences that admit (or Lipschitz continuous) utility functions, smooth-utility-rational choice, representations interval orders.
