标题： Towards gravitational QNM spectrum from quantum spacetime

摘要： 非对易Schwarzschild背景上引力波轴向模的有效势被给出。 非对易性通过半Killing型Drinfeld扭曲从微分同胚的变形Hopf代数引入。分析在度规和非对易性参数的一阶摄动下进行。这导致了一个修正的Regge-Wheeler势，在与经典Regge-Wheeler势相比时，最显著的差异出现在接近视界处。 显示英文摘要

摘要： The effective potential for the axial mode of gravitational wave on noncommutative Schwarzschild background is presented. Noncommutativity is introduced via deformed Hopf algebra of diffeomorphisms by means of a semi-Killing Drinfeld twist. The analysis is performed up to the first order in perturbation of the metric and noncommutativity parameter. This results in a modified Regge-Wheeler potential with the strongest differences in comparison to the classical Regge-Wheeler potential being near the horizon.
