Extremal sizes of subspace partitions

Olof Heden, Juliane Lehmann, Esmeralda Nastase +1

A subspace partition $Π$ of $V = V (n, q)$ is a collection of subspaces of $V$ such that each 1-dimensional subspace of $V$ is in exactly one subspace of $Π$ . The size of $Π$ is the nu…

On the existence of a (2,3)-spread in V(7,2)

Olof Heden, Papa A. Sissokho

An $(s, t)$ -spread in a finite vector space $V = V (n, q)$ is a collection $F$ of $t$ -dimensional subspaces of $V$ with the property that every $s$ -dimensional subspace of $V$ …
