论文摘要
论文研究互补的选择功能，即单调和一致的选择功能。在工作\ cite {ry}中引入并使用了这种选择功能，以调查与互补合同的比赛。给出了构建此类功能的三种（通用）方式：通过前题学，作为完全互补（或预购）选择功能的直接图像，并借助超模块化设定功能。
The paper studies complementary choice functions, i.e. monotonic and consistent choice functions. Such choice functions were introduced and used in the work \cite{RY} for investigation of matchings with complementary contracts. Three (universal) ways of constructing such functions are given: through pre-topologies, as direct images of completely complementary (or pre-ordered) choice functions, and with the help of supermodular set-functions.
