Overgroups of regular unipotent elements in simple algebraic groups

نویسندگان

چکیده

We investigate positive-dimensional closed reductive subgroups of almost simple algebraic groups containing a regular unipotent element. Our main result states that such do not lie inside proper parabolic unless possibly when their connected component is torus. This extends the earlier Testerman and Zalesski treating subgroups.

Regular Elements in Algebraic Groups of Prime Characteristic

A result of Steinberg's on the existence of rational regular unipotent elements in quasi-split simple algebraic groups over fields of arbitrary characteristic is partially extended to the case of non-quasi-split groups.

Computing in Unipotent and Reductive Algebraic Groups

The unipotent groups are an important class of algebraic groups. We show that techniques used to compute with finitely generated nilpotent groups carry over to unipotent groups. We concentrate particularly on the maximal unipotent subgroup of a split reductive group and show how this improves computation in the reductive group itself.

Algebraic Groups I. Unipotent radicals and reductivity

In class, we have proved the important fact that over any field k, a non-solvable connected reductive group containing a 1-dimensional split maximal k-torus is k-isomorphic to SL2 or PGL2. That proof relied on knowing that maximal tori remain maximal after a ground field extension to k, and so relies on Grothendieck’s theorem. But for algebraically closed fields there is no content to Grothendi...

On Mordell-Lang in Algebraic Groups of Unipotent Rank 1

In the previous ICERM workshop, Tom Scanlon raised the question of whether the (classical, i.e., non-dynamic) Mordell-Lang conjecture remains true in algebraic groups of unipotent rank 1 (with additional hypotheses on the closed subvariety X ). I will discuss some initial work in progress on this question, focusing on the Lang exceptional set of X . Conventions and Basic Definitions For this ta...

On One Class of Unipotent Subgroups of Semisimple Algebraic Groups

This paper contains a complete proof of a fundamental theorem on the normalizers of unipotent subgroups in semisimple algebraic groups. A similar proof was given later by A. Borel and J. Tits (see also bibliographical remarks in the introduction to their paper). I.I. Pyatetskii–Shapiro suggested me to prove the following theorem which in his opinion would be of interest for the theory of discre...
