On solvable Lie algebras of small breadth
Borworn Khuhirun, Korkeat Korkeathikhun, Songpon Sriwongsa +1
The concept of breadth has been used in the classification of p-groups and nilpotent Lie algebras. In this paper, we investigate this notion for finite-dimensional solvable Lie alg…

Nilpotent varieties in symmetric spaces and twisted affine Schubert varieties
Jiuzu Hong, Korkeat Korkeathikhun
We relate the geometry of Schubert varieties in twisted affine Grassmannian and the nilpotent varieties in symmetric spaces. This extends some results of Achar-Henderson in the twi…
