Residual hermite normal form computations

Abstract

This paper extends the class of Hermite normal form solution procedures that use modulo determinant arithmetic. Given any relatively prime factorization of the determinant value, integral congruence relations are used to compute the Hermite normal form. A polynomial-time complexity bound that is a function of the length of the input string exists for this class of procedures. Computational results for this new approach are given. © 1989, ACM.
