Boolean circuits of polynomial size and polylogarithmic depth are given for computing the Hermite and Smith normal forms of polynomial matrices over finite fields and the field of rational numbers. The circuits for the Smith normal form computation are probabilistic ones and also determine very efficient sequential algorithms. Furthermore, we give a polynomial-time deterministic sequential algorithm for the Smith normal form over the rationals. The Smith normal form algorithms are applied to…

This paper shows how to apply fast matrix multiplication techniques to the problem of triangularizing a matrix over a ring using elementary column operations to lead to an algorithm for triangularizing integer matrices that has a faster running time than the known Hermite normal form algorithms.
Hermite form computation of matrices of differential polynomials
TLDR
The Hermite form H of A is computed by reducing the problem to solving a linear system of equations over F(t), which requires a polynomial number of operations in F in terms of the input sizes: n, degDA, and degtA.

TLDR
The method employs randomization as a tool to remove the iterations along the main diagonal in the classical sequential algorithms, and as such might be useful in similar settings, as well as may speed the sequential methods themselves.
