Imre Bárány, Benjamin Doerr:Balanced Partitions of Vector SequencesLet d, r ∈ N and ¦¦ · ¦¦ be any norm on Rd . Let B denote the unit ball with respect to this norm. We show that any sequence v1,v2, ... of vectors in B can be partitioned into r subsequences V1, ... , Vr in a balanced manner with respect to the partial sums: A similar bound holds for partitioning sequences of vector sets. Both results extend an earlier one of Bárány and Grinberg (1981) to partitions in arbitrarily many classes. Mathematics Subject Classification (1991): 11K38 Keywords: Discrepancy, partition, linear algebra
