.... z) f(x, y) # (z # (# n i=1 x i ) The claims on the properties of f, g follow from a theorem on the composition of MSP s (see [30] the well known fact that threshold functions have linear MSP complexity and that a function and its dual have the same MSP complexity (see e.g. 21] In [1], the monotone function ODDFACTOR is studied. This function is defined on bipartite graphs on t = # n pairs of vertices, where an input graph can be specified by n Boolean variables, one for each of the potential edges.

....pairs of vertices, where an input graph can be specified by n Boolean variables, one for each of the potential edges. An input graph is accepted if and only it contains an odd factor, i.e. a subgraph in which every vertex has odd degree (in particular degree 0) The following result is proved in [1]: Theorem 9 The ODDFACTOR function on n variables can be computed by an MSP over GF (2) of size n, but a monotone Boolean circuit computing the function must have size n# (log n) Now suppose we are given a monotone Boolean circuit family that for any n computes ODDFACTOR on input graphs ....
