Lower bounds for some explicit decision problems over the complex numbers are given. The decision problems considered are certain zerodimensional subsets of N×C, and can be assimilated to a countable family of polynomials gi. More precisely, one should decide for input (i, x) if gi(x) = 0. A lower bound for deciding if a polynomial gi vanishes at some x can be derived from an uniform lower bound for the evaluation of all f ∈ (gi). That bound is obtained by means of an arithmetic invariant of… CONTINUE READING
