Of special interest in summability theory are those conservative matrices possessing the "mean-value property". If c A ={x: Ax ∊ c} denotes the convergence domain of a conservative matrix A, then A has the mean-value property in case, for each x in c A , there exists M = M(A, x) > 0 such that 1 This property has been considered by many writers and has been shown, among other things, to be equivalent to the requirement that the matrix be associative, i.e., for each x in c A 2
