Abstract:

Let $V$ be a finite vector space over a finite field of order $q$ and of characteristic $p$. Let $G\leq GL(V)$ be a $p$-solvable completely reducible linear group. Then there exists a base for $G$ on $V$ of size at most $2$ unless $q \leq 4$ in which case there exists a base of size at most $3$. This extends a recent result of Halasi and Podoski and generalizes a theorem of Seress. A generalization of a theorem of Pálfy and Wolf is also given.
