A geometric description of the m-cluster categories of type D_n
Karin Baur, Bethany Marsh
We show that the m-cluster category of type D_n is equivalent to a certain geometrically-defined category of arcs in a punctured regular nm-m+1-gon. This generalises a result of Sc…
Richardson elements for parabolic subgroups of classical groups in positive characteristic
Karin Baur, Simon M. Goodwin
Let be a simple algebraic group of classical type over an algebraically closed field . Let be a parabolic subgroup of and let $\p = \Lie P$ be the Lie algebra of …
A geometric description of -cluster categories
Karin Baur, Bethany Marsh
We show that the -cluster category of type is equivalent to a certain geometrically-defined category of diagonals of a regular -gon. This generalises a result of…
A class of gradings of simple Lie algebras
Karin Baur, Nolan R. Wallach
In this paper we give a classification of parabolic subalgebras of simple Lie algebras over that satisfy two properties. The first property is Lynch's sufficient condi…
