A Seifert fiber space is a specific type of 3-manifold that can be characterized by its fibered structure. It is named after Wolfgang Seifert, who developed this concept in the 1930s. Formally, a Seifert fiber space is defined as follows: 1. **Base space**: It is constructed using a 2-dimensional base space, typically a 2-dimensional orbifold.
