Halton-type sequences from global function fields

For any prime power q and any dimension s ≥ 1, a new construction of （t, s）-sequences in base q using global function fields is presented. The construction yields an analog of Halton sequences for global function fields. It is the first general construction of （t, s）-sequences that is not directly based on the digital method. The construction can also be put into the framework of the theory of （u, e, s）-sequences that was recently introduced by Tezuka and leads in this way to better discrepancy bounds for the constructed sequences.
