在本文中,广义尖是具有严格凸边界的适当凸流形,它与封闭欧几里得流形微分同态。这些是由Ballas, Cooper和Leitner分类的[J]。Topol. 13 (2020), pp. 1455-1496。标记模空间同胚于表示的共轭类空间的子空间。它有一种描述是对痕量变化的概括,另一种描述涉及权重数据,类似于描述半简单李群的描述。它也是欧几里得相似(共形平面)结构空间上的束,纤维是三次微分空间中的闭锥。对于可定向的广义尖端,纤维同胚于实体环面上的锥体。参考文献
ln this paper, a generalized cusp is a properly convex manifold with strictly convex boundary that is diffeomorphic towhereis a closed Euclidean manifold. These are classified by Ballas, Cooper, and Leitner [J. Topol. 13 (2020), pp. 1455-1496]. The marked moduli space is homeomorphic to a subspace of the space of conjugacy classes of representations of. It has one description as a generalization of a trace-variety, and another description involving weight data that is similar to that used to describe semi-simple Lie groups. It is also a bundle over the space of Euclidean similarity (conformally flat) structures on, and the fiber is a closed cone in the space of cubic differentials. For-dimensional orientable generalized cusps, the fiber is homeomorphic to a cone on a solid torus. References
