Let be a vector in the space with ring of integers and be a positive integer, a polynomial in with coefficient in. The exponential sum associated with is defined as , where the sum is taken over a complete set of residues modulo. The value of depend on the estimate of cardinality , the number of elements contained in the set where is the partial derivatives of with respect to. To determine the cardinality of , the p-adic sizes of common zeros of the partial derivative polynomials need to be
