Algebra Seminar

Infinitesimal one-parameter subgroups and exponentiation


Friday 31st August, 12:05--12:55pm, Carslaw 175


Paul Sobaje (University of Melbourne)


Infinitesimal one-parameter subgroups and exponentiation


Let \(G\) be a semisimple algebraic group over a field of characteristic \(p\). In this talk, we will describe the varieties of infinitesimal one-parameter subgroups of \(G\), and discuss their importance in representation theory. We will also consider a related question which deals with the existence of certain Springer isomorphisms between the nilpotent variety of \(\mathrm{Lie}(G)\) and the unipotent variety of \(G\).


After the seminar we will take the speaker to lunch.

See the Algebra Seminar web page for information about other seminars in the series.
