Presentation of Borel subgroups of Kac-Moody groups over local rings

Robynn Corveleyn

We obtain presentations of Borel subgroups of certain Chevalley groups and Kac-Moody groups of simply laced type. More precisely, we show that Borel subgroups of simply laced Cheva…

Representing in Low Rank I: conjugacy, topological and homological aspects

Robynn Corveleyn, Geoffrey Janssens, Doryan Temmerman

In this series of papers, we investigate properties of a finite group which are determined by its low degree irreducible representations over a number field $F$ , i.e. its represent…

Lie type quotients of the maximal unipotent subgroup of Kac-Moody groups of type $HB_{2}^{(2)}$

Robynn Corveleyn

In this article, we construct infinite families $(G_{n})_{n \in N}$ of finite simple groups $G_{n}$ of Lie type, such that the rank of $G_{n}$ strictly increases as $n$ tends to…
