9404522 Petters The research entails applications of concepts in differential geometry and singularity theory (mainly caustics) to the study of deflection of light from distant sources where matter intervenes. Such gravitational lensing gives insights into distributions of matter within various types of galaxies. The research has potential applications to theoretical astrophysics, astronomy and general relativity. ***

小行星9404522 这项研究需要应用微分几何和奇点理论（主要是焦散线）中的概念来研究来自物质干涉的遥远光源的光的偏转。这样的引力透镜效应让我们了解到 不同类型星系中物质的分布。该研究在理论天体物理学、天文学和广义相对论方面具有潜在的应用价值。 ***
