Affiliations: | Algebra and Mathematical Logic | Keywords: | Chromatic symmetric function;Dumbbell graphs;e−Positivity;Sun graphs | Issue Date: | 1-Mar-2025 | Rank: | M22 | Publisher: | Elsevier | Journal: | Discrete Mathematics | Abstract: | We introduce two classes of graphs - suns and dumbbells, both with few variations and explore their chromatic symmetric function and its e-positivity. We also give many connections of these two classes with other classes of connected graphs. |
