For a special class of graphs F that we will call flower graphs and their double coverings  F’, we generalize this divisibility by showing that the Tutte polynomial evaluation T_{F} (x, 1) divides T_{F’} (x, 1), and interpret the resulting quotient as a sum over negative vector felds on F.</p>}, number={1}, journal={Minnesota Journal of Undergraduate Mathematics}, author={Verma, Kaustubh}, year={2021}, month={Jul.} }
