In geometry, a "hedgehog" refers to a specific topological structure that can be visualized as a shape resembling the spiny animal after which it is named. More formally, in the context of topology and geometric topology, a hedge-hog is often defined as a higher-dimensional generalization used in various mathematical contexts.
