摘要
A spider graph is a tree with at most one vertex of degree greater than 2. A graceful labeling of a tree T with n edges is a bijection f : V (T) -> {0, 1, 2, ... , n} g such that {|f(u) - f (v)| : {u, v} is an edge of T} = {1, 2, ..., n}. We show that some classes of spider graphs admit graceful labeling.
