Relative Bruhat decomposition of wonderful compactification
Fei Chen, Shang Li
In the seminal paper of Borel and Tits about reductive groups, they show some fundamental results about Bruhat cells with respect to a minimal parabolic subgroup, e.g., relative Br…

Wonderful embedding for group schemes in the Bruhat--Tits theory
Shang Li
For a reductive group over a discretely valued Henselian field , using valuations of root datum and concave functions, the Bruhat--Tits theory defines an important class of…

Lagrangian Mean Curvature Flow in Pseudo-Euclidean Space II
Shanshan Li, Jiaru Lv, Rongli Huang
In this paper, we consider the mean curvature flow of entire Lagrangian graphs with initial data in the pseudo-Euclidean space, which is related to the special Lagrangian parabolic…
