摘要:
We study the maximal number of pairwise distinct columns in a ?-modular integer matrix with m rows. Recent results by Lee et al. provide an asymptotically tight upper bound of O (m(2)) for fixed ?. We complement this and obtain an upper bound of the form O(?) for fixed m, and with the implied constant depending polynomially on m.
