The main purpose of this research project is to study symmetries of manifolds, with particular attention paid to symmetries of 4-dimensional manifolds. The problems to be studied vary from general questions concerning the geometric structure of exotic space forms and 4-dimensional manifolds to many specific problems connected with the existence of symmetric and asymmetric manifolds. The broad spectrum of methods which will be employed in this research include the techniques of surgery and homotopy theory, transformation groups, differential geometry and gauge theory. Since manifolds are very natural geometric objects, including spheres and tori, for example, and since symmetry is a very natural geometric property, techniques for treating symmetry of manifolds are important to cultivate.

该研究项目的主要目的是研究流形的对称性，特别注意4维流形的对称性。 要研究的问题因有关外来空间形式的几何结构和4维流形的一般问题而异，到与对称和不对称流形的存在有关的许多特定问题。 这项研究中将采用的广泛方法包括手术和同型理论的技术，转化组，差异几何和量规理论。 例如，歧管是非常自然的几何对象，包括球体和托里，并且对称性是一种非常自然的几何特性，因此处理歧管对称性的技术对于培养很重要。
