Local-global principles for the existence of Levi factors
David Harbater, Julia Hartmann, George McNinch
We discuss local-global principles for the existence of Levi factors (i.e., complements to the unipotent radical) for linear algebraic groups over one-variable function fields. We…

Levi decompositions of a linear algebraic group
George J. McNinch
If G is a connected linear algebraic group over the field k, a Levi factor of G is a reductive complement to the unipotent radical of G. If k has positive characteristic, G may hav…
