%0 Journal Article %T Partitions and Indivisibility Properties of Countable Dimensional Vector Spaces %A C. Laflamme %A L. Nguyen Van The %A M. Pouzet %A N. Sauer %J Mathematics %D 2009 %I arXiv %X We investigate infinite versions of vector and affine space partition results, and thus obtain examples and a counterexample for a partition problem for relational structures. In particular we provide two (related) examples of an age indivisible relational structure which is not weakly indivisible. %U http://arxiv.org/abs/0907.3771v2
