On the Location of Roots of Independence Polynomials

WebThe independence polynomial of a graph G is the function i(G, x) = ∑ k≥0 i k x k, where i k is the number of independent sets of vertices in G of cardinality k. We prove that real roots of independence polynomials are dense in (−∞, 0], while complex roots are dense in ℂ, even when restricting to well covered or comparability graphs.

WebThis means that the number of roots of the polynomial is even. Since the graph of the polynomial necessarily intersects the x axis an even number of times. If the graph intercepts the axis but doesn't change sign this counts as two roots, eg: x^2+2x+1 intersects the x axis at x=-1, this counts as two intersections because x^2+2x+1= (x+1)* (x+1 ...
