Starlike tree
In the area of mathematics known as graph theory, a tree is said to be starlike if it has exactly one vertex of degree greater than 2. This high-degree vertex is the root and a starlike tree is obtained by attaching at least three linear graphs to this central vertex.
Properties
Two finite starlike trees are isospectral, i.e. their graph Laplacians have the same spectra, if and only if they are isomorphic.[1]
gollark: What latency? You can automatically switch out tapes, for even more money.
gollark: Well, it would be worth it after... a few hundred terabytes, probably.
gollark: Wait, how much are LTO8 tape *drives*?
gollark: ¡¡¡
gollark: Premining.
