If you have a question about this talk, please contact David Craven. A linear algebraic group f in V* such that ^{G}f(v) is not zero. It is called ‘geometrically reductive’ if this condition holds when we allow f to be instead a polynomial invariant of arbitrary finite degree. Note that the maximum degree d required may depend on the choice of V in general. One might reasonably say a group is ‘globally reductive’ if there is a finite number d which works for any G-module V. This condition lies between the two notions of reductivity.It is straightforward to show that any group whose identity component is linearly reductive is globally reductive; we will report on progress towards proving that these are the only globally reductive groups.
