On F-polynomials of thistles
A general formula is derived for the F-polynomial of thistles - a family of graphs obtained by attaching twigs (hinged edges) to all the nodes of a basic member. The formula involves a function which is identified explicitly for certain types of F-polynomials. The function is then used to partially characterize a special family of thistles.
