The character sheaves on the group compactification
Xuhua He
We give a definition of character sheaves on the group compactification which is equivalent to Lusztig's definition in \cite{L3}. We also prove some properties of the character she…
Closures of Steinberg fibers in twisted wonderful compactifications
Xuhua He, Jesper Funch Thomsen
By a case-free approach we give a precise description of the closure of a Steinberg fiber within a twisted wonderful compactification of a simple linear algebraic group. In the non…
The -stable pieces of the wonderful compactification
Xuhua He
Let be a connected, simple algebraic group over an algebraically closed field. There is a partition of the wonderful compactification of into finite many -stab…
Unipotent variety in the group compactification
Xuhua He
The unipotent variety of a reductive algebraic group plays an important role in the representation theory. In this paper, we will consider the closure $\bar{\Cal U}$ of the uni…
