Semisimple subalgebras in simple Lie algebras and a computational approach to the compact Clifford-Klein forms problem

Maciej Bocheński, Piotr Jastrzębski, Anna Szczepkowska +2

In this paper we develop algorithms of finding homogeneous spaces of semisimple non-compact Lie groups which do not admit compact Clifford-Klein forms. We propose a computer progra…
