论文摘要
我们开发了算法和计算机程序，这些算法和计算机程序验证了在半同质空间上离散群体行为的适当性的标准。我们应用这些算法来查找对均质空间上不连续的非连续群体行为的新示例，这些算法不接受适当的SL（2，R）actions。
We develop algorithms and computer programs which verify criteria of properness of discrete group actions on semisimple homogeneous spaces. We apply these algorithms to find new examples of non-virtually abelian discontinuous group actions on homogeneous spaces which do not admit proper SL(2,R)-actions.
