A multilinear extension of an n person cooperative game is a polynomial in n variables, defined by assigning to each coalition S the polynomial v(S)$$\prod_{i\in S}x_ i\prod_{j\not\in S}(1-x_ j)$$. Multilinear extensions have applications in the theory of power indices of games, and they reflect composition of games in a useful way.
