WebHowgrave-Graham [5] reformulated Coppersmith’s techniques and proposed the following result and it shows that if the coe cients of h(x 1;x 2;:::;x n) are su -ciently small, then the equality h(x 0;y 0) = 0 holds not only modulo N but also over integers. The generalization of Howgrave-Graham result in terms of the Eu-clidean norm of a ...
