Abstract
A vector space partition of GF(q)^v is a collection of subspaces such that every nonzero vector is contained in a unique element. We improve a lower bound of Heden, in a subcase, on the number of elements of the smallest occurring dimension in a vector space partition. To this end, we introduce the notion of q^rdivisible sets of ksubspaces in GF(q)^v. By geometric arguments we obtain nonexistence results for these objects, which then imply the improved result of Heden.
