New preprint: simple algebraic groups…

New paper at joint with Bob Guralnick: Simple algebraic groups are (usually) determined by an invariant ( A very special case of our main results is a description of groups of type E8.   Update (6/3/2014): The paper now has a new title “Simple groups stabilizing polynomials”. Update (5/2015): It will be published in Forum of Mathematics, Pi.
