DESCRIPTION:Title: A1-subgroups and their unipotent elements\n\nAbstract:
Let G be a simple algebraic group over an algebraically closed field of
prime characteristic\, and let u be a unipotent element of G. In this t
alk I will discuss when there exists a unique A1-subgroup of G containin
g u. This follows from recent work\, joint with Donna Testerman\, in whi
ch we establish to what degree an analogue of the Jacobson--Morozov Theo
rem for Lie algebras can be stated for simple algebraic groups defined o
ver fields of (good) positive characteristic.
