Query: A Few More Trees the Chromatic Symmetric Function Can Distinguish   A well-known open problem in graph theory asks whether Stanley's chromatic
symmetric function, a generalization of the chromatic polynomial of a graph,
distinguishes between any two non-isomorphic trees. Previous work has proven
the conjecture for a class of trees called spiders. This paper generalizes the
class of spiders to $n$-spiders, where normal spiders correspond to $n = 1$,
and verifies the conjecture for $n = 2$.
