\(P_3\) and \(P_3^*\) Convexities
摘要
In this chapter, we study the convexities \(P_3\) and \(P_3^*\) in more depth. Despite the geodesic convexity being the most traditional, many results of the \(P_3\) and \(P_3^*\) convexities are used to obtain results in the geodesic convexity, mainly related to computational complexity and, therefore, we decided to present them first.
