摘要 Let the coronas C<sub>n</sub>⊙K<sub>1</sub> be the polygons with one additional end-point for eachvertex.Thom Grace conjectured that C<sub>n</sub>⊙K<sub>1</sub> are harmonious for n even.In this paper,aproof of his conjecture is given. Let the coronas C_n⊙K_1 be the polygons with one additional end-point for eachvertex.Thom Grace conjectured that C_n⊙K_1 are harmonious for n even.In this paper,aproof of his conjecture is given.
