Hermite Normal Forms and Δ-vector
Let δ(P) = (δ0, δ1, . . . , δd) be the δ-vector of an integral polytope P ⊂ R of dimension d. Following the previous work of characterizing the δvectors with ∑d i=0 δi ≤ 3, the possible δ-vectors with ∑d i=0 δi = 4 will be classified. And each possible δ-vectors can be obtained by simplices. We get this result by studying the problem of classifying the possible integral simplices with a given δ...
متن کاملHermite and Smith Normal Forms ofTriangular Integer Matrices
This paper considers the problem of transforming a triangular integer input matrix to canonical Hermite and Smith normal form. We provide algorithms and prove deterministic running times for both transformation problems that are linear (hence optimal) in the matrix dimension. The algorithms are easily implemented, assume standard integer multiplication, and admit excellent performance in practi...

متن کاملFast Computation of Hermite Normal Forms of Random Integer Matrices
This paper is about how to compute the Hermite normal form of a random integer matrix in practice. We propose significant improvements to the algorithm by Micciancio and Warinschi, and extend these techniques to the computation of the saturation of a matrix. Tables of timings confirm the efficiency of this approach. To our knowledge, our implementation is the fastest implementation for computin...
متن کاملAsymptotically Fast Computation of Hermite Normal Forms of Integer
This paper presents a new algorithm for computing the Hermite normal form H of an A 2 Z Z nm of rank m together with a unimodular pre-multiplier matrix U such that UA = H. Our algorithm requires O~(m ?1 nM(m log jjAjj)) bit operations to produce both H and a candidate for U. Here, jjAjj = maxij jAijj, M(t) bit operations are suucient to multiply two dte-bit integers, and is the exponent for mat...
